摘要

研究重点是开发一种低成本、便携、低功耗、准确有效的皮肤电响应(GSR)采集系统。用于刺激电流传递的甚高频正弦波发生器采用宽带宽双JFET运算放大器设计，工作频率范围为10khz至45khz。通过为系统提供USB电源，并提供LabVIEW和MATLAB接口进行进一步处理，可以方便地使用单个笔记本电脑，从而保持可移植性和电源隔离。开发的系统已被校准并用于获得情绪刺激的皮肤反应。从获得的数据中有效地识别出两种类型的情绪。

Design and development of portable galvanic skin response acquisition and analysis system

The work concentrated on developing a low-cost, portable, low power, accurate and effective Galvanic Skin response (GSR) acquisition system. Very High Frequency sinewave generator for stimulating current delivery is designed using a wide bandwidth dual JFET Operational Amplifier functioning at specific frequencies in the range 10 KHz to 45 KHz. The portability and power isolation is maintained by providing a USB powered supply to the system with a LabVIEW and MATLAB interface for further processing, which can be facilitated using a single laptop. The developed system has been calibrated and employed for acquiring emotionally stimulated skin response. Two types of emotions are recognized efficiently from the acquired data.
