Ingestible Sensor

Published By: IndustryARC Published On : 29-Nov-2022

Ingestible sensing capsules is fast emerging critical technology that has the potential to impact health, nutrition, and clinical areas. These ingestible devices are non-invasive and are very attractive to customers. High-tech sectors are responsible for creating digital pills, and they are developing quickly, necessitating producers to innovate. Researchers are developing pill-sized sensors to identify medicinal compounds and perhaps even diagnose other digestive disorders. 

Additionally, this real-time healthcare technology has the potential to go far beyond what is currently possible with sensors. Ingestion-based sensor technology is the advancement after wearable sensor technology. In the areas of disease management, monitoring, and diagnosis, it is a disruptive technology. 

Historical Context:

Early reports of ingestible monitoring devices, known as endoradiosonde, were published as early as the 1950s, establishing the area of ingestible electromechanical devices for medical uses. Many early sensors were created to track mechanically based physiological biomarkers in the gut, such as intraluminal pressure and motility. Early examples of endoradiosonde also included ingestible instruments for pH monitoring and hemorrhage detection. Many significant device components and form factors were standardized in the first generation of ingestible devices.

The first generation of ingestible electromechanical devices liberated a wealth of imagination and creativity but also revealed significant limitations, inherent dangers, and engineering difficulties. The stochastic emptying of the stomach, which results in wildly varying durations for gastric transit between people and fed vs. fasted states, for example, is a significant design problem. Early research also indicates that the anatomical transitions between the stomach and small and large intestines, the pyloric antrum and cecum, respectively, were delayed in the passage of the device. 

Moreover, recent developments in transitory and bioresorbable electronics, biocompatible batteries, biodegradable polymers, and other smart materials have given ingestible electromechanical devices new ideas and possibilities. These most recent developments are the result of important breakthroughs in materials, processing, and system integration.

Recent Advances in Ingestible Electronic Devices:

The second generation of ingestible medical devices was made possible by the miniaturization of electronics, advancements in electrochemical storage, and innovation in microelectronic components, whereas the first generation of ingestible electromechanical systems was based on advances in circuit design and microwave communications. These scientific and technological advancements were combined in a system typical of the time known as the "Ingestible Thermal Monitoring System," which NASA created in the 1980s. This tool was capable of accurately measuring human subjects' core body temperatures in a variety of settings, including ambulatory ones. These gadgets might be powered by on-board Ni-Cd batteries for up to 72 hours. 

When utilised for telemetry, magnetic fields can extend the detection range up to 1m, enabling remote signal transduction. Recent developments in transitory and bioresorbable electronics, biocompatible batteries, biodegradable polymers, and other smart materials have given ingestible electromechanical devices new ideas and possibilities. These most recent developments are the result of important breakthroughs in materials, processing, and system integration.

Advanced Materials for Next-Generation Ingestible Devices: 

As the importance of gut health continues to grow, ingestible medical gadgets are likely to become more and more common and play a major role in the Gastrointestinal Therapeutics market. Orally administered pharmaceuticals will be optimally given with maximal bioavailability, thanks to smart drug delivery devices with on-board sensors and patient monitoring systems. These delivery methods are ideal for active substances with short serum half-lives or organ-specific adsorption. Currently, data on intestinal morphology, physiological indicators, intraluminal gas concentrations, and the presence of blood can be measured, recorded, and sent by Ingestible Sensors. 

Future technologies in the gastrointestinal therapeutics market may be able to sample and sequence longitudinal changes in the microbiome's composition that are related to food or physiology. Present-day ingestible electromechanical devices frequently make use of COTS electronics, packaging, and power sources. The usage of medical devices that can be ingested could increase with the development of new materials that make equipment flexible and biodegradable, reduce toxicity, and increase functionality. Longitudinal diagnostics and drug delivery technologies could be made possible by an affordable device with an appropriate form factor that can be used to manage and treat chronic diseases.

Electronic Sensors (ESs) and Future Combinations:

The U.S., and European markets already have Ingestible Electronic Sensors (IESs) available for cardiovascular disease, diabetes, and gastrointestinal therapeutics market. For instance, Proteus Digital Health created a wearable sensor (also known as a Patch) that records metrics like heart rate, activity, and body position in addition to time-stamped, patient-logged events that are typically produced when the patient logs an event by swallowing a grain-of-sand-sized IES. Once it touches the stomach, the IES turns on and communicates with the Patch that is worn on the skin. 

Data is gathered and wirelessly transmitted to a mobile computing device using the patch. Ingestion events are organized and displayed by compatible software. The patient can also share the data with a doctor using the system. It is hoped that taking the IES along with medicines can increase patient adherence. Since 2010, Proteus' wearable sensor, including the IES, has been CE-marked in Europe. To legally sell a device in Europe, it must bear the CE mark.

Otsuka Pharmaceutical's Abilify MyCite, a drug-device combination therapy combining Proteus's IES and Otsuka's Abilify, was given FDA approval for the New Drug Application (NDA) in 2017. (Aripiprazole, a drug that is used to treat adults with schizophrenia, bipolar I disorder, and major depressive disorder). In this product, the IES is physically integrated into the medication tablet rather than being physically isolated from the active pharmaceutical ingredient. 

On the one hand, the development of digital pills depends greatly on the judicious administration of intellectual human capital. It should be emphasized that it costs a lot of money to produce the digital pills with ingestible sensors known as the Abilify MyCite technology, and the top experts had to be retained. On the other hand, a thorough evaluation of medical technology is equally crucial. According to GoodRx, a generic form of Abilify typically costs between US$500 and US$800 a month. More than $1600 is required to purchase the initial digital pills with ingestible sensors, like Abilify MyCite.

The FDA has just recently approved a few new IES products, with Abilify MyCite being the first "digital pill." As an illustration, Proteus, Fairview Health Services, and the University of Minnesota Health recently announced the creation of the first "digital oncology pill," which combines Proteus's IES and the chemotherapeutic drug capecitabine, to aid patients with stage three and four colorectal cancers. By enabling them to track their daily medication intake and access data on their objective medication ingestion, activity level, as well as self-reported mood and rest, this system has been created to assist patients with serious mental illness in facilitating more open dialogue with their healthcare team. In the hopes of increasing adherence, patients can choose to share this information with certain members of their care team and family using the MyCite App.

An IES in the form of a capsule that can detect several intestinal gases, including oxygen, carbon dioxide, and hydrogen, has recently been reported by researchers at the RMIT University in Melbourne, Australia, and others. The researchers hope to eventually market the technology through their newly founded company, Atmo Biosciences, and see this gas capsule as a possible diagnostic tool for several gastrointestinal illnesses, including irritable bowel syndrome.

Scientists at the Massachusetts Institute of Technology (MIT) in Cambridge, USA, have created a "bio" IES combination product that combines engineered probiotic sensor bacteria and ultra-low-power microelectronics packed in a single capsule. This product can detect gastrointestinal bleeding in vivo and opens new opportunities for improving the management and diagnosis of disease. Additionally, the application of IESs to the treatment of drug-resistant tuberculosis shows potential due to the current therapy's reliance on direct observations, which has been demonstrated to be ineffective.

Healthcare providers might be able to target their efforts more effectively on patients who don't take their prescriptions as directed with the use of IESs, which would also help patients pay for fewer trips to medical facilities. Additionally, IESs may greatly enhance adherence to pre-exposure prophylaxis, daily medication for HIV transmission prevention.

Significant Potential for Savings in Healthcare Costs:

By lowering the need for patients to stay in hospitals and for emergency medical care, digital pills offer a huge potential to reduce healthcare expenses. The annual costs of non-compliance in the US range from $100 billion to 290 billion dollars, in Europe they are EUR1.25 billion, and in Australia, they are about USD7 billion. 

Additionally, 10% of hospitalizations among the elderly are brought on by noncompliance with prescribed treatments; a typical noncompliant patient requires three extra doctor visits annually, raising treatment expenses by USD 2,000 annually as a result. Improved noncompliance is expected to result in cost savings of between USD 661 million to USD 1.16 billion in the diabetes industry. Consequently, non-adherence is a serious clinical and financial issue.

Patent Analysis:

The United States, the European Patent Office, Canada, Australia, and China are the countries that issued the most patents, accounting for 72% of all patents worldwide.

The dynamics of patent applications and grants between 2010 and 2018 were shown to be increasing steadily. Most applications (49) were submitted in 2017, and most patents (15) were awarded in 2018. A focus on commercialization and the introduction of new ideas to the market rather than the filing of new patents may explain the lower level of patent activity in the years 2019–2022, which corresponds to the first half of the year. 

The main patent holders for digital pills with ingestible sensors are Proteus Digital Health Inc. (Redwood City, CA, USA), Otsuka Pharmaceutical Co., Ltd. (Tokyo, Japan), Given Imaging Ltd. (Yokneam, Israel), Pop Test Abuse Deterrent Technology LLC (Cliffside Park, NJ, USA), Given Imaging Inc. (Duluth, GA, USA), Innurvation Inc. (Glen Burnie, MD, USA), Otsuka America Pharmaceutical Inc. (Rockville, MD, USA), Pop Test LLC (Cliffside Park, NJ, USA), Progenity Inc. (San Diego, CA, USA), The Smart Pill Corporation (Buffalo, NY, USA), and others. 

A body-associated receiver that may be external or implanted was described by the patent's petitioners, Proteus Biomedical, Inc. The methods and systems for using a receiver to communicate with dosage distribution systems are also covered. Multi-mode communication ingestible event markers and systems, as well as their applications, were described by the patent's inventors (Proteus Biomedical, Inc., Redwood City, CA, USA). 

The integrated circuit component, upper and lower electrodes, and an ingestible event marker are combined to form an ingestible event marker. When the ingestible event marker meets stomach fluid, the current flows through the integrated circuit, causing one or more functional blocks in the circuit to emit a detectable signal. The materials used to make the upper and lower electrodes are different. These are the principal businesses dedicated to growing the digital pill market through creative development. Their innovations are in the areas of endoscopic diagnostics and mobile clinical no smart medication delivery. 

Digital tablets with sensors are used in mobile clinical monitoring and medicine delivery, which can be used for a variety of diseases in a wide spectrum of patients. Capsule endoscopy can discover issues with gastrointestinal peristalsis, including chronic nausea, gastroparesis, acid reflux, and colon cancer. Ingestible sensors for digital pills are currently quite expensive.

Ethical Challenges:

IESs have a significant deal of promise to improve healthcare. The stakeholders (such as researchers, engineers, healthcare professionals, patients, ethicists, and regulatory authorities) need to be aware of these ethical concerns and address them in a cooperative effort as early as feasible in the development process of these technologies. Many patient-related issues are brought up by IESs, but the ethical questions of autonomy and informed consent stand out. It is crucial to achieve full voluntary and informed permission because IESs would, at least initially, involve therapies that patients are unfamiliar with. However, as IES devices have a separate software component, using them will need agreeing to user agreements, which many patients find difficult to understand and which most users frequently do not read. Uncertainty exists around whether the click-through user agreement can entirely or partially replace informed consent.

Additionally, IESs bring up provider-centred ethical concerns. On the one hand, it is hoped that IESs will enhance the interaction between the physician and the patient by helping the clinician to better comprehend what is happening (biologically and/or socially) with the patient and so facilitate more open communication between the two. However, some patients could feel as though their medical professionals are unintentionally spying on them using such systems. The decision is at its most voluntary when a patient requests an IES rather than the non-IES formulation of the same medication. Other times, the pressure could be slight or overt. Think about a patient who only uses the IES formulation because their insurer will only pay for it or a patient who does it to appease their family. The efficient use of IES products is based on a trusting doctor-patient relationship where honest communication is encouraged and not suppressed. These are not simple seas to traverse. The makers of IESs must prepare in advance for requests for data in both civil and criminal situations.

Lastly, IESs present moral concerns that go beyond the patient-care team relationship. After all, IES items will probably cost more than equivalent non-IES variants, especially once the non-IES version has lost its market exclusivity. It makes sense for people to demand evidence that the patient is utilising the product and that it is giving them enough additional benefits to guarantee the costs. Transparency regarding all pertinent IES product characteristics is also required to maintain public trust in these products. Makers of IES, for instance, must proactively report security lapses, such as ransomware attacks.

Legal Challenges:
  • In the U.S. and Europe, wearable sensors, including IESs, are considered medical devices. A medical device in the U.S. is defined under section 201(h) of the Federal Food, Drug, and Cosmetic Act and can be anything from a straightforward tongue depressor to a sophisticated robotic surgery tool or an in vitro diagnostic product like a test kit or reagent. Particularly, a medical device, unlike normal medicine, does not fulfill its primary intended functions by chemical action and is not dependent on being digested for such achievement.
  • Medical devices intended for human use in the U.S. are categorized into three classes by the FDA: Class I, which includes low-risk devices like patient scales, Class II, which includes moderate-risk devices like sickle-cell test kits, and Class III, which includes high-risk devices like new heart valves. Class III is automatically assigned to new devices. However, the "De Novo" classification procedure gives sponsors the chance to ask the FDA to classify their innovative devices into Class I or II based on a risk-based assessment.
Recent Developments:
  • In June 2022, Massive Bio and AdhereTech, two of NYC Digital Health’s 100 most promising start-up companies, announced a partnership. The partnership is to provide integrated access to precision oncology care for cancer patients. Both companies recently contracted with leading pharmaceutical companies and major specialty pharmacies.
  • In January 2021, etectRx, Inc., announced that it has entered into an agreement with Pear Therapeutics, Inc. This agreement is to develop two product candidates in the Central Nervous System (CNS) space combining Prescription Digital Therapeutics (PDTs) and adherence sensors. The collaboration is the first of its kind to explore the use of digital pill solutions with PDTs.
  • In August 2020, Otsuka America Pharmaceutical, Inc., announced that it has completed its acquisition of Proteus Digital Health, Inc. The acquisition includes assets and intellectual property for its ingestible and wearable sensor technology. The acquisition of Proteus assets and intellectual property will serve as a catalyst for implementing the next phase of the digital medicine program.
  • In July 2020, Proteus Digital Health acquired Otsuka Pharmaceutical. Proteus, founded in 2001, develops ingestible sensors and a wearable sensor patch to track medication-taking behaviour. The "smart pill" maker's sensor was one of the first of its kind to receive clearance from the Food and Drug Administration (FDA). Once valued at $1.5 billion, Proteus raised a total of $420 million from investors. 
  • In January 2019, Proteus Digital Health has launched digital oncology medicines to improve patient outcomes, which is the first health system in the world to prescribe digital capecitabine, a common chemotherapy drug prescribed with the Proteus ingestible sensor. It is being used to help treat stage 3 and 4 colorectal cancer patients.
Various Applications of Ingestible Sensors:

Diseases of the Nervous System

The methods used by Proteus Digital Health Inc., are a striking illustration of an active innovation strategy for developing digital pills with ingestible sensors. This company's innovations are frequently utilised in neurology and psychiatry. The system consists of a conductive element, an electronic component, and a material-dependent partial power supply. Upon coming into touch with a conducting liquid, which completes the power supply and generates a voltage potential, the system is activated. The electrical component controls the conductance between the various materials to provide a particular current signature. The technology can be used for a variety of purposes, including the development of pharmaceutical compositions with pharma-informatics capabilities and ingestible event markers and identifiers.

Digital tablets with ingestible sensors developed by Proteus Digital Health have been shown to have a high therapeutic efficacy, a good safety profile, and the potential to greatly raise the patient quality of life in clinical trials. However, additional post-marketing clinical trials with more patients and strong evidence are required.

HIV/AIDS

Inventions from Proteus Digital Health are frequently used to track patient adherence in HIV-positive patients. In the clinical trial, the Proteus digital health feedback system was examined to track and improve antiretroviral medication adherence in 130 HIV-positive patients who were at least 18 years old and had subpar adherence. Compliance monitoring with digital pills also offers significant advantages in the prevention and treatment of HIV since patient adherence to a pharmaceutical therapy plan is crucial to prevent or avoid costly consequences for the patient or the community.

Pain control

Pain management for diverse pathological diseases is another medical field that makes extensive use of digital pills with ingestible sensors. By using digital pills, doctors may verify that a patient truly took their prescribed medications when it was time for them to be delivered. This is a vital device for preventing the unintended selling of pharmaceuticals that haven't yet been taken. Tremeau Pharmaceuticals, Inc. focuses on providing non-opioid painkillers to patient populations with clearly defined needs. To control pain more efficiently and with fewer side effects, the business has developed digital painkillers. For individuals with cancer pain that has proceeded to that stage, opioid analgesics are an essential part of treatment. Pain management is a necessary and crucial component of treatment for cancer patients. Long-term usage of opioid analgesics in cancer patients raises concerns about the possibility of long-term negative effects, including probable abuse and addiction.

As a result, the ability to record with digital tablets the consumption of a medicine or other actual exposure of the body to medicine, including pain management, has many significant therapeutic advantages. Owing to this monitoring capability, patients are confident that they are correctly taking their prescribed medications. This information helps prevent the danger of over-prescription of medications.

Cardiovascular diseases

Additionally, digital pills used in cardiology give the physician an accurate dose-response curve that displays the patient's response to medication and the moment at which it was given. There are numerous uses for these data. As a result, the doctor can determine, for instance, which patients do not respond to the medication in the tablet. Such patients might not be included in a study to evaluate the therapeutic efficacy of a particular drug. This guarantees that the trial will only involve people who respond favourably to the test drug. This advancement will increase the effectiveness of drugs and motivate patients to take less ineffective treatments. It might also be used to monitor who took their medication in clinical trials.

In the clinical trial, the researchers control persistent hypertension while participants were receiving chronic antihypertensive medication. The system recorded when each tablet was taken, the number of steps taken daily, the duration and frequency of patients' sleep, as well as their circadian rhythms for activity and relaxation. By decreasing side effects including weariness of the heart muscle and rebound effects, among others, and adjusting the dosage and timing for each patient, digital pills enable doctors to titrate to the most effective dosages of cardiac medications.

Diabetes

New technologies that embed or attach to the skin to continually measure blood sugar levels have just entered the market. They are systems that can be linked to other compatible medical equipment and electronic interfaces, including insulin pumps, automated insulin delivery systems, blood glucose metres, and other diabetes management tools. The innovation EP3108810 A1 (Valtronic Tech) provides an ingestible device for measuring the glucose levels in the small intestine (Holding). For a brief data transmitter/receiver, the ingestible device has a retainer to hold it in place in the small intestine. The method of the invention comprises activating the device, securing the device in the small intestine using a retainer, measuring data related to glucose concentration inside the small intestine via a glucose sensor, and transmitting the data related to the glucose concentration to a receiver located outside the small intestine, particularly for determining or predicting the glucose level in the subject's bloodstream.

As a result, in addition to the patenting of digital pills with ingestible sensors for the treatment of diabetes, glucose sensors for displaying the blood and small intestine glucose levels of a patient with diabetes mellitus as well as for smart drug administration are also protected by a patent.

Gastroenterology

In the gastrointestinal therapeutics market, digital pills with ingestible sensors are frequently employed. For the treatment of gastrointestinal illnesses including inflammatory bowel disease, better treatment plans are still desperately needed. Ingestible sensing capsules are fast emerging as a major technology has the ability to create a positive impact in the Gastrointestinal Therapeutics market. These protocols must have the ability to deliver treatments to regions of the gastrointestinal tract while minimising or avoiding the side effects of oral or other systemic administration. Therapeutic drugs occasionally need to be injected into areas of the small or large intestine to treat or lessen the symptoms of various medical conditions. As opposed to delivering the medication orally, this is more effective. For instance, medicinal medications may be administered directly to the small intestine, completely avoiding the stomach's gastrointestinal system. This would enable the delivery of a greater dose to a particular area of the small intestine. There are numerous ingestible capsules containing sensors for the gastrointestinal therapeutics market that are designed to take images from inside the body's cavities and passageways, including the cavities and passageways of the GI tract. These devices frequently include both illumination light sources and an enclosed digital camera. The capsule can be powered by batteries or external inductive power transmission. A radio transmitter and memory for transmitting data to an external receiver outside the body may also be resent in the capsule.

Ingestible Sensor Products:

ABILIFY: ABILIFY is embedded with the Proteus ingestible sensor, for serious mental illness. This product digitally records medication ingestion. ABILIFY securely measures patient medication-taking patterns and selects physiological data and self-reported behavioural information. This information helps individuals and their healthcare professional team better manage patients’ serious mental illnesses. This Digital Medicine would be used in the treatment of adults with schizophrenia, acute treatment of manic and mixed episodes associated with bipolar I disorder, and as adjunctive therapy for the treatment of major depressive disorder.

ABILIFY MYCITE (aripiprazole tablets with sensor): 

ABILIFY MYCITE is a drug-device combination product comprised of Otsuka’s oral aripiprazole tablets embedded with an Ingestible Event Marker (IEM) sensor. ABILIFY MYCITE, an atypical antipsychotic, is indicated in adults for the treatment of schizophrenia, acute manic and mixed episodes. It provides an objective summary of drug ingestion over time, to help enhance collaboration with healthcare providers who treat patients with certain serious mental illnesses. The wearable patch receives a message from the sensor in the pill, which is how the device operates. Patients monitor their drug intake on their smartphones by using a mobile application it receives information from the patch. Patients also authorize their careers and doctors to access the data through a web-based portal.

Ingestible CorTemp Sensor: 

CorTemp Ingestible Core Body Temperature Sensor wirelessly transmits core body temperature as it travels through the digestive tract. The sensor’s signal passes harmlessly through the body to the CorTemp Data Recorder worn on the outside of the body. It helps patients for preventing heart illnesses. The recorder picks up the data and converts them into digital format for analysis. Within 1 to 2 hours of ingesting, the CorTemp pill reveals vital information necessary for the prevention and treatment of heat-related illnesses.

CapsoCam Plus: 

CapsoCam Plus provides the most comprehensive imaging available in capsule endoscopy. CapsoCam Plus offers a full 360o panoramic direct lateral view of the small intestinal mucosa to enhance diagnostic capacity. External receiver hardware is not required at all with CapsoCam Plus’s better massive onboard storage system. The faster and simpler capsule administration made possible by this wire-free onboard storage solution also eliminates the dangers of radio frequency emissions.

The New Generation of Drug Carriers- Micro- and Nano-Motors:

Micro/nanomotors (MNMs) are miniature machines that are capable of converting a variety of energies into mechanical motion. Researchers are interested in them as potential drug carriers in the treatment of cancer owing to their good permeability and regulated motility. Micro/nanomotor drug delivery systems can significantly increase therapeutic effectiveness and lessen the negative effects of anticancer medications as compared to conventional formulations. Although magnetic field-driven micro/nanomotor drug delivery systems have the benefits of long propulsion duration and great delivery precision, they also clearly have drawbacks. For instance, it is challenging to adjust the magnetic field or set a precise gradient. Additionally, drug-loaded particles' poor affinity for metals results in limited loading efficiency for micro/nanomotor drug delivery systems. Eventually, it's important to pay close attention to the chronic long-term impacts brought-on by the presence of many metals in the human body. Disadvantages such as short lifetime and lower sensitivity making micro- and nano-motors are not an efficient drug delivery system than ingestible sensors.

Microneedles for Drug Delivery:

Microneedles (MNs), a transdermal delivery system that combines the technology of transdermal patches and hypodermic needles, have seen a rise in research and development over the past several years. Since the needles are extremely small, in the range of hundreds of microns, they cause little or no discomfort. They do have a drawback though, as successful implantation into the stratum corneum layer of the skin depends on the biodegradable substance having enough mechanical strength. Ingestible sensors can be directly swallowed by mouth and don’t have this type of disadvantages making ingestible sensors an effective drug delivery system than microneedles.

Millimetre-scale Transceiver:

Imec, a research institute for nanoelectronics and digital technologies in Leuven, Belgium, has created a wireless receiver and transmitter that can fit inside a millimeter-scale capsule. According to the International Maritime Employers' Council team, the most significant achievement is that the module does not require a crystal-based oscillator. Such oscillators are commonly used to precisely stabilize the frequency of radio signals and network protocol timing, but the Imec researchers developed an on-chip mechanism that, in effect, calibrates itself using the wireless network.

Biosensor-integrated Drug Delivery Systems:

A multidisciplinary technological innovation called biosensor-integrated drug delivery systems enables precise drug monitoring and delivery. Drug administration and continuous monitoring are made possible by cutting-edge medical equipment called biosensor-integrated drug delivery systems. For chronic diseases including diabetes mellitus, cancer, and cardiovascular diseases as well as advancements in regenerative medicine, the usage of smart polymer, bioMEMS, and electrochemical sensors has been intensively researched for these systems. 

The technique essentially consists of sensors made for continuous study of biological components, followed by drug release in response to signals. The benefits include quick drug release and great sensitivity.

Conclusion

Ingestible sensors are still a new concept, and the idea of swallowing a sensor containing all the electronic components remains a psychological challenge. Strict safety guidelines must be maintained by pharmaceutical companies and regulatory authorities. The field must also surmount the huge hurdle of massive expenditures linked to product development, as these technologies require the invention of new integrated technologies, an issue that could slow the speed of development. 

Nevertheless, the information that can be obtained through this ingestible technology which has a huge potential to shed light on newly discovered functionalities of the gut and the digestive system, which in turn contributes to the growth of the gastrointestinal therapeutics market. The development and use of ingestible electromechanical devices could present a variety of opportunities and challenges. The next generation of ingestible medical devices must be developed by integrating new materials with device manufacturing techniques. 

Most ingestible devices described are passive systems that transit the GI tract via peristalsis. There are many opportunities to design and deploy devices that are capable of autonomous location. The potential clinical significance of ingestible electromechanical devices is undoubtedly only constrained by our imagination and inventiveness give the quick advancements in materials, fabrication, device design, and robotics. 

Hence, people can safely assume that these highly integrated ingestible sensors are the future of gut health. The widespread adoption of digital pills into clinical practice is still hindered by several obstacles, despite the advancements that have been made in this area to date. They encompass, among other things, concerns with therapeutic effectiveness, safety, treatment costs, and privacy.
