Does anyone know if there's a sensor in existence that can detect human touch behind solid piece of plastic (no direct contact with sensor)?
Capacitive sensors can do it.
Other than that, buttons can too be behind a piece of plastic.

Thanks! Buttons are out of the question, it's a rigid plastic in old fashion telephone handset.
Yep. I'm just playing with capacitive sensors and a jam jar lid on the end of a wire can easily detect my hand from 10cm away.
(that's about 4 inches in old money)
