人体电触觉信息测试系统的研制

The development of a human electrotactile testing system

水文介绍为了进行皮肤电触觉研究而研制的测试系统，它包括信号发生器，刺激器，电极等部分，采用计算机控制信号波形，恒流源输出。

In modern biomedical engineering, people use tactile communication aids for the blind and the deaf.One problem about it is the low capacity of tactile sensory channel.Since there is virtually research made on the physiology of multichannel stimulli, we burld this clectrotactile measuring system with the purpose of obtaining some detailed and reliable data. The system consists of 4 parts,the computer con trolled digital-analog converter,the voltage-Ampere converter,the power source and electrode.The output is 2 way impulse currnet source.
