I would appreciate any ideas for putting together a circuit, perhaps using OP AMPS, to measure the change in human skin resistence as a potential method for a "relaxtion" device.
assuming the human body, between left and right hands may have a 'dry' skin value of 50KΩ, a small change needs to be detected. Perhaps a differential amplifier?
I am looking forward to any ideas.
thanks,
Art
