摘要

本文设计了一种生物遥测装置，用于监测长期植入过程中电极-组织接触(ETC)的复杂阻抗。它包括执行所提出的测量技术的可植入无线设备，以及支持PC和植入物之间双向通信的外部控制器。它使用数字正弦波形方法来刺激ETC，同时记录256个恢复电位的样本。实验验证，频率和幅值可分别设定在4 Hz~210 kHz范围内，plusmn14muA~1.5mA范围内。

Wireless implantable sensing device for in-vivo monitoring of electrode-tissues contact variation

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.
