生物医学传感器(或称换能器)是一种用来提取和捕捉生物体内各种生理信息(如心电、脑电等生物电和心音等),并将其转换为易处理的电量的一种装置(或器件)。它已成为生物医学测量,数据处理,信息转换、诊断、治疗、监护、遥测、控制等等工作中不可缺少的器件,在医学测量系统中占有重要的地位。也是实现医学现代化和许多 Biomedical sensors (or transducers) are used to extract and capture biological information (such as ECG, EEG and other bio-electricity and heart sounds, etc.), and convert it to easily handle the amount of electricity Device (or device). It has become an indispensable device in biomedical measurement, data processing, information conversion, diagnosis, treatment, monitoring, telemetry, control and so on. It occupies an important position in the medical measurement system. It is also the realization of medical modernization and many
