Abstract
A device for proximity detection includes multiple electrodes and an impedance sensor coupled to the electrodes. The impedance sensor may include three impedance elements and a sensing element arranged in a bridge configuration to offset an external impedance and detect changes to impedance in the environment of the device. The device further includes a proximity detector that obtains sensor measurements between multiple subsets of electrodes and analyzes the sensor measurements to determine whether an object is approaching the device.
