DUAL MEASUREMENT FOR HIGH SENSITIVITY CAPACITIVE SENSING APPLICATIONS AND RELATED SYSTEMS, METHODS AND DEVICES

Abstract:

Disclosed embodiments relate, generally, to a dual measurement technique for capacitance sensing, and related systems and methods. In one embodiment, a capacitance sensing method characterized by moisture tolerance is performed and another capacitance sensing method characterized by proximity tolerance is performed. In one embodiment, the method characterized by moisture tolerance is a driven-shield self-capacitance sensing measurement, and the method characterized by proximity tolerance is a grounded-shield self-capacitance sensing measurement.
