An Anti-Static Wristband is a wristband worn to safely ground people involved in electronic manufacturing, in order to prevent electronic discharge. The wristband protects the person against a shock. The wristband is usually made of carbon and the wristband is connected to the ground by a stretchable coil. The ground connections in industry are made to an Earth Bonding Point, whereas personal connections will be used by a crocodile clip.
There are also ankle straps, which are not usually connected to the ground and are used in cases where the person is needed to move around, like a surgical theatre.
