A Low Power Radio Telemetry Achieving Very High Data Rates at Biocompatible Frequencies

Abstract

This papers reports a solution for a low power, high data rate telemetry, intended to be used in capsule endoscopy. The system is taking advantage of the small absorption of radio waves of low frequencies, around 120 MHz, to allow a telemetry up to a million bit per second of raw data, while keeping the power consumption to 6 mW. The system does not need the design of a dedicated ASIC and therefore reduces the costs of prototyping. The dimensions of the transmitter can be kept small enough to be implantable, and an implementation on a flexible substrate has been performed.
