Abstract
A capacitive proximity sensor with a stacked electrode structure where an inner electrode is partially screened by an upper one. The self-capacitances of selected electrodes is measured while other electrodes are held to ground or to a shield potential. In this manner, the proximity sensor estimates a value of the dielectric permittivity of the approaching body.
