A "Microelectronic Pill" is basically a multi-channel sensor used for remote biomedical measurements using micro technology. This has been developed for the internal study and detection of diseases and abnormalities in the gastrointestinal tract (GI) where restricted access prevents the use of the traditional endoscope.
The invention of the transistor allowed the first use of radiometry capsules, which used simple circuits for the internal study of the gastrointestinal tract (GI). They could not be used because they could transmit only from a single channel and also due to the size of the components. They also suffered from poor reliability, low sensitivity and short device lifetimes.
This led to the application of single-channel telemetry capsules for the detection of diseases and abnormalities in the gastrointestinal tract where the restricted area prevented the use of traditional endoscopy.
Subsequently they were modified since they had the disadvantage of using laboratory type sensors such as glass pH electrodes, resistance thermometers, etc. They were also large. The subsequent modification is similar to that of the previous instrument but is smaller in size due to the application of existing semiconductor manufacturing technologies. These technologies led to the formation of "MICROELECTRONIC PILL".
The microelectronic pill is basically a multi-channel sensor used for remote biomedical measurements using micro technology. This is used for real-time measurement parameters such as temperature, pH, conductivity and dissolved oxygen. The sensors are manufactured by electron beam and integration of photolithographic patterns and were controlled by an application-specific integrated circuit (ASIC).
