Claim Text:
1. A wearable device, comprising: a first housing portion having a conductive section and a non-conductive section, the conductive section being connected to ground; a second housing portion including a printed circuit board with a conductor on the printed circuit board surface positioned beneath the non-conductive section of the first housing portion, the conductor on the printed circuit board surface and the conductive section of the first housing portion forming a capacitor of a capacitive sensor; and capacitive sensor circuitry, operatively coupled to the conductor on the printed circuit board surface, wherein the capacitive sensor circuitry drives a voltage of the conductor on the printed circuit board surface to create a capacitive charge between the conductor on the printed circuit board surface and the conductive section of the first housing portion.
