Abstract :
This work describes a novel triple-band bio-telemetry system that is implemented using a miniaturized implantable antenna and triple-band communication circuits for implantable applications. The proposed miniaturized implantable antenna effectively covers three bands for 402 MHz at MICS (medical implant communications service) band, 433 MHz and 2.4 GHz at ISM (industrial, scientific, and medical) band by using radiator of π-shape with stacked and spiral structure. This triple-band communication circuits consist of a 402 MHz data transmission telemetry and a 433 MHz wireless powering transmission circuit, as well as a 2.4 GHz wake-up controller circuit. The system was successively integrated and could substantially improve the life-time of the implantable device.
