Abstract
A detector is shown for detecting manually applied pressure. A substrate defines a position of activation and electrodes are mounted on this substrate. A processing device is energized such that the electrodes are configured to identify a position of applied pressure by detecting a change in resistance in response to a first energizing signal received from the processing device. Furthermore, the electrodes are configured to confirm this position of applied pressure by detecting a change in capacitance in response to a second energizing signal received from the processing device. The electrodes comprise a first electrode located on an upper surface which detects the change in capacitance, and second and third electrodes which detect the change in resistance.
