Publication number: 20230408300Abstract: 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.Type: ApplicationFiled: June 7, 2023Publication date: December 21, 2023Inventors: Sébastien GRISOT, Jerald G. OTT, III
