Abstract
A wireless anti-static device is disclosed, including an electronic sensing circuit that measures the polarity and electrostatic potential of the subject relative to its surroundings. Ion guns of positive and negative polarities are able to transfer an arbitrary quantity and polarity of charge from the subject by ejecting ionized air molecules into the surrounding environment. A control unit is programmed to trigger the appropriate ion gun when a corresponding charge is measured on the body, in order to continually maintain the net charge on the body below a desired threshold. The subject is thus effectively grounded relative to its environment without requiring physical tethers to ground.
