Abstract
In one embodiment, a method includes applying a drive signal to a first electrode of a sensor to generate an electric field extending at least in part from the first electrode toward a second electrode of the sensor. The electric field includes a first portion and a second portion, and the first portion extends farther away from a plane of the first electrode than the second portion. The method also includes shunting the second portion of the electric field away from the second electrode and receiving a sense signal from the second electrode produced at least in part by the first portion of the electric field. The sense signal indicates whether an object has come within proximity of the sensor.
