Is there a sensor that can detect when skin touches?

Question

i need a sensor that detect when skin touches it it needs to be tiny and long like a metal contact, like when you touch the plug of a speaker and the speaker makes a buzzing sound... i need a sensor that can register the static electro effect of skin to kinda complete a circuit without shocking the person....in talking to much

Answer 1

there used to be toys in the early nineties that you would put in your hand it it started to make noises and blink lights. It was very small and had two metal electrodes, i don't know how its made, but you can research on skin conductivity, because thats what happened then, ther was two contacts and the skin was the bridge. good luck

Answer 2

There are capacitive switches and capacitive sensors that do this. Google them.
