摘　　要：设计并制作了一种可用于电化学遥测的嵌入式微系统,可配合电化学传感器实现时间-电流法、循环伏安法、方波伏安法等基本的电化学检测方法。该微型电化学系统的硬件包括电化学传感器接口模块、处理器模块和通信模块等,均采用单端供电。系统的传感器接口模块可向传感器提供±1100mV范围内的工作电位,通信模块可采用无线方式接收远程终端的遥测命令,并将测试结果传回远程终端。分别采用电阻、葡萄糖生物传感器对系统性能进行了测试,表明该系统能够实现基本的电化学检测功能,可以用于环境遥测、生物医学遥测和其他一些无人值守的电化学监测.An embedded electrochemical system available for wireless telemetry is designed and constructed. The system realized a few electrochemical techniques such as amperometry, cyclic voltammetry and square wave voltammetry. The system consists of an interface to electrochemical sensors, process unit and communication module, all of which are single-supply powered. The interface to electrochemical sensors can polarize the sensors in the range from -1100 mV to 1100 mV. The communication module can receive the remote commands and send the data acquired back to the remote terminals. The telemetry system was tested by using resistors as dummy cells and glucose biosensors, which showed that the system was available for environmental telemetry, medical telemetry and electrochemical detection with no man on duty.
