Adjusting to Skin Resistence

by Carson Reynolds

While tinkering over the last few days I’ve had an idea. One common thing is to include a resistor ladder or potentiometer in GSR designs, to tune the circuit to different skin resistances. I think a better approach might be to use a voltage-controlled resistor to set up either gain or a resistance for comparison so that it matches the user’s skin. I will work to build up a prototype sooner than later.
