Abstract

A multi-channel capacitive sensing structure which includes a member on a first side has a first surface with two or more electrically conductive regions separated from one another by a non-conductive boundary, and two or more insulated conductors arranged on a second non-electhcally conductive surface, on a second side of the member opposing the first side, spaced from each conductive region by the member and capacitively coupled thereto.
