PROJECT TITLE :

Electrotactile Display with Real-Time Impedance Feedback Using Pulse Width Modulation

ABSTRACT :

An electrotactile show could be a tactile interface composed of skin surface electrodes. The utilization of such a device is limited by the variability of the elicited sensation. One possible answer to this downside is to watch skin electrical impedance. Previous studies revealed a correlation between impedance and threshold, however did not construct real-time feedback loops. During this study, an electrotactile display was created using a one.45 murm s feedback loop. Real-time pulse width modulation was proposed, and the relationship between skin resistance and absolute threshold was measured to search out a function for determining a suitable pulse width from skin resistance. An analysis experiment revealed that the proposed algorithm suppressed spatial variation and reduced temporal amendment.
