Abstract

We developed a general purpose electro-tactile stimulator that can configure with computer to generate different pattern of current waveforms. Four independent channel are provided in this system. Additionally, for one time programming by computer and multiple use by other devices, digital I/Os are embedded which serve as trigger input and output. User is being able to turn on or off each channel online without interrupting other channels and intensity of the main channel is modifiable online too. Sweeping (scanning) method has been benefited to make the system smaller and more cost effective.
