ABSTRACT:
One embodiment in accordance with the invention includes a capacitive sensor apparatus that includes a sensing element and a ground element. The capacitive sensor apparatus also includes a floating strike ring that is electrically isolated from the sensing element. The floating strike ring and the ground element form a spark gap. The spark gap is for reducing potential damage to the capacitive sensor apparatus that can be caused by an electrostatic discharge encountered by the capacitive sensor apparatus.
