Electric charge detector - Projets LABS | Elektor Magazine

This is mend as a handy tool to warn you for possible ESD risks. Whenever you approach this small circuit with charged objects (like plastic bags) the LED will start lighting up. After a few seconds of inactivity the LED will slowly dim again. If you move antistatic bags in front of it, it will not respond. The minimalistic design uses only a JFET (transistor), a diode and a LED.
