Swallowable biotelemetry systems are one kind of implantable biotelemetry systems. The research about swallowable biotelemetry systems is rapidly growing recently because they can be used to measure physiological and pathological parameters of human gastrointestinal tracts in vivo and they significantly improve patient comfort. This paper presents the current research of swallowable biotelemetry systems domestically and abroad. The development trend of these systems is analyzed at the end of the paper.

The advent of semiconductor technology in the mid-20th century created unprecedented opportunities to develop a new generation of small-scale wireless medical sensing devices that can support remote monitoring of patients' vital signs. The first radio pills were developed as early as the 1950's using only a few transistors. These swallowable capsules could sense and wirelessly transmit vital parameters from inside the human body.

Aim: To propose a new, non-invasive method for monitoring 24-h pressure, temperature and pH value in gastrointestinal tract.
Methods: The authors developed a miniature, multi-functional gastrointestinal monitoring system, which comprises a set of indigestible biotelemetry capsules and a data recorder. The capsule, after ingested by patients, could measure pressure, temperature and pH value in the gastrointestinal tract and transmit the data to the data recorder outside the body through a 434 MHz radio frequency data link.

Heart rate (HR) and systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure were recorded by biotelemetry in nine conscious unrestrained sloths for 1 min every 15 min over a 24-h period. The animals were allowed to freely move in an acoustically isolated and temperature-controlled (24 +/- 1 degree C) experimental room with light-dark cycle (12/12 h). Behavior was closely monitored through a unidirectional visor and classified as resting (sitting or suspended), feeding (chewing and swallowing embauba leaves, Cecropia adenops), or locomotor activity around the tree trunk or on the room floor.
