Abstract
The present disclosure provides a capacitive touch sensor for an electronic device. The touch sensor has a trace carrier having a sensing surface, a connecting surface, and a number of electrically conductive traces on the trace carrier. The traces form a sensing pattern on the sensing surface and pass from the sensing surface to the connecting surface. The sensor also includes a capacitive sensing circuit operable to electrically couple to the traces at the connecting surface of the trace carrier, and to sense a capacitance change. A touch position on the sensing surface is determined dependent upon the sensed capacitance change.
