Abstract :
Wireless bio-telemetry links using implanted sensors and antennas are promising for a continuous monitoring of physiological data and for analyzing tissues. However these sensors need to be very small and biocompatible. The present work focuses on the design of bio-compatible passive micro LC sensors. Materials necessary for an implanted sensor are analyzed, as well as their impacts on the design. It is queried by an external antenna and from the input admittance measurements, the characteristics of the encapsulating tissue is obtained. Simulations have been performed with realistic tissue models which are readily available for experimental testing.
