Certain voltage tester probes rely on body capacitance. A capacitive touch sensor responds to close approach (but not force of touch) of a part of a human body, usually a fingertip. The capacitance between the device itself and the fingertip is sensed. Capacitive touch screens don't require applying any force to their surfaces, which makes them easier to use and design in some respects. Furthermore, because of body capacitance, people act as good antennas, and some small televisions use people to enhance reception.
