Abstract :
This paper concerns the design of a biotelemetry device dedicated to monitor the complex impedance of the electrode-tissues contacts (ETC) on long term implantations. It consists of an implantable wireless device performing the proposed measurement technique, and an external controller supporting the bi-directional communications between a PC and the implant. It uses a digital sine waveform approach to stimulate the ETC while recording 256 samples of the restituted potential. Experimental validation confirms frequency and amplitude can be respectively set within the range of 4 Hz~210 kHz, and plusmn14muA~1.5mA.
