一种体内外无线通信系统及其供电和通信分时复用方法
技术领域
本发明涉及植入式芯片技术领域,特别涉及一种体内外无线通信系统及其供电和通信分时复用方法。
背景技术
将医疗器械植入人体内监测体内部某些生理参数如血压、血糖、激素水平等是一个全新的研究方向,其意义重大。为了实现植入式医疗器械能够获取人体内的生理数据,需要攻关的核心技术为体内外能量供给、植入式传感器、体内外数据通信等。其中现有的主流体内外数据通信技术大多是基于低频近场通信来进行信号传输,现有的主流体内外远距离无线供电技术基本是基于磁共振技术,这样的一个集无线通信和无线供电一体的植入式系统在体内需要两个线圈,一个用于数据通信发射、另一个用于能量接收;同理在体外也需要两个线圈。
由于体内外线圈处于相近的空间中,体内通信线圈所发射的能量一般在毫瓦级别,而体外供电发射线圈的发射功率一般在数瓦级别。如果体内通信线圈和体外供电线圈同时工作的话,供电发射线圈发射的能量会严重干扰通信能量,极大影响体内外通信距离和准确率。
发明内容
本发明针对现有技术的缺陷,提供了一种体内外无线通信系统及其供电和通信分时复用方法,将能量供给和数据传输分开,使两者互相不干扰,提高测量准确率。
