    I played with electronics in the past and some special IC chips they recommend you do not touch them as you can destroy them. I played with piezo speakers these are found in many electronic devices but they can also be used as a microphone and are extremely sensitive. I would place one on the door knob inside the house and if anyone touched the outside door handle I would know. Using a piezo speaker and an amplifier you can turn a switch on or off we used for lamps and many other things.
