Abstract
A structure for reducing or eliminating electrostatic discharge from a finger into the platen of a biometric sensor is disclosed. The structure is designed to be positioned above and around the platen such that conductive components in the structure stimulate corona discharge and dielectric breakdown from an approaching finger into the conductive components of the structure rather than into the platen itself. The structure is designed to eliminate, reduce or otherwise neutralize the charge on an approaching finger prior to the finger coining into contact with the platen of the biometric sensor and prior to the finger coming close enough to the platen so that the electrostatic discharge causes an are to strike the platen.
