摘要

介绍了一种基于单片机的生理数据记录仪的设计与实现。该设备被设计用于接收来自商用GSR仪器的皮肤电反应(GSR)数据，将它们存储在其板载存储器中，然后通过串行端口将它们中继到计算机。设计的重点是便携性和低功耗的电池驱动的移动应用。提出了一种特殊的数据压缩算法，以优化板载内存的使用，减少数据传输到计算机的时间。采用PIC微控制器作为数据流协调的中央控制单元。数据记录仪原型测量18/spl次/9/spl次/3厘米，并且可以使用SMT或混合技术轻松小型化。

A microcontroller-based data logger for physiological sensing

The design and implementation of a microcontroller-based data logger for recording physiological data is presented. The device is designed to receive galvanic skin response (GSR) data from a commercial GSR instrument, store them on its on-board memory, and relay them later to a computer via the serial port. The focus of the design is on portability and low power consumption for battery-driven ambulatory applications. A special data compression algorithm is developed to optimize the on-board memory usage and reduce the data transfer time to a computer. A PIC microcontroller is used as the central control unit for the data flow coordination. The data logger prototype measures 18/spl times/9/spl times/3 cm, and can be readily miniaturized using SMT or hybrid techniques.
