Stun belt
A stun belt is a belt fastened around the subject's waist, leg, or arm that carries a battery and control pack, and contains features to stop the subject from unfastening or removing it. A remote-control signal is sent to tell the control pack to give the subject an electric shock. Some models are activated by the subject's movement.
The electrical pulse delivered by the control pack is based on the waveform developed by Jack Cover, which he called the TASER.
These devices are used to control prisoners in the United States and elsewhere in the world. One type is the REACT belt (see below). Some stun belts can restrain the subject's hands and have a strap going under his groin to stop him from rotating the belt around his waist to reach its battery and control pack and trying to deactivate it. Stun belts are not generally available to the public.
