These physically connect to the body via hand electrodes, footpates, foot-tubs, or TENS pads. Electric current carries the audio frequencies into the body to cause vibration and resonance. These devices transfer their energy through the skin and have some limitations as regards full body penetration.
Since the body is a semiconductor with approximately 1 million ohms of resistance, penetration of contact energy is somewhat limited unless a radio carrier is also used.
Do not use a contact device if you are wearing a pacemaker or have a heart condition.
