Physiological monitoring would entail minimal risk, discomfort, or restriction of mobility.

Telemetry systems of a type that have been proposed for the monitoring of physiological functions in humans would include the following subsystems:

• Surgically implanted or ingested units that would comprise combinations of microelectromechanical systems (MEMS)- based sensors [bioMEMS sensors] and passive radio-frequency (RF) readout circuits that would include miniature loop antennas.
• Compact radio transceiver units integrated into external garments for wirelessly powering and interrogating the implanted or ingested units.
