CAPACITIVE MEASURING DEVICE WITH SWITCHED ELECTRODES FOR TOUCHLESS CONTACTLESS INTERFACES

摘要

The present invention relates to a capacitive-measurement device for touch-sensitive and/or contactless interfaces, including at least one capacitive-measurement electrode (1) and electrode-switching means (2) capable of electrically connecting said at least one electrode (1), either to capacitive-measurement means or to a guard potential (11), said at least one capacitive-measurement electrode (1) and said electrode-switching means (2) being provided on a single detection surface (7) according to a technique for manufacturing planar electronic components. The invention also relates to an apparatus implementing the device.
