“…The WEC swallowing approach was first proposed in the preliminary communication article [8] on RF transmission of temperature and pressure data from the human GI tract. Currently, WCE has been established as a safe and convenient tool for the diagnosis and treatment of GI tract diseases and disorders, including GI bleeding, small intestine tumours and Crohn’s and Celiac diseases.…”

Implantable sensor systems are effective tools for biomedical diagnosis, visualization and treatment of various health conditions, attracting the interest of researchers, as well as healthcare practitioners. These systems efficiently and conveniently provide essential data of the body part being diagnosed, such as gastrointestinal (temperature, pH, pressure) parameter values, blood glucose and pressure levels and electrocardiogram data. Such data are first transmitted from the implantable sensor units to an external receiver node or network and then to a central monitoring and control (computer) unit for analysis, diagnosis and/or treatment. Implantable sensor units are typically in the form of mobile microrobotic capsules or implanted stationary (body-fixed) units. In particular, capsule-based systems have attracted significant research interest recently, with a variety of applications, including endoscopy, microsurgery, drug delivery and biopsy. In such implantable sensor systems, one of the most challenging problems is the accurate localization and tracking of the microrobotic sensor unit (e.g., robotic capsule) inside the human body. This article presents a literature review of the existing localization and tracking techniques for robotic implantable sensor systems with their merits and limitations and possible solutions of the proposed localization methods. The article also provides a brief discussion on the connection and cooperation of such techniques with wearable biomedical sensor systems.

“…With the development of radio-transmitting pHsensitive capsules (Jacobson and Mackay, 1957;Noller, 1961), the study ofpH changes in the gastrointestinal tract has been greatly facilitated, and once inaccessible regions can now be investigated. Disorders of small bowel function producing malabsorption and diarrhoea are not uncommon after gastric surgery and are due to such factors as diminished pancreatic secretion, inadequate mixing of food and digestive enzymes, and intestinal hypermotility.…”

“…The development of radiotransmitting pH-sensitive capsules (Jacobson and Mackay, 1957;Noller, 1960) has provided a new technique for the measurement of pH within the gastrointestinal tract. Noller (1962) and Connell and Waters (1964) have reported their experiences with this technique in the measurement of gastric acid secretion.…”
