发明名称 TOUCH SENSOR
摘要 A touch sensing method and a touch sensing device (100) are described for sensing a location of a touch. When the touch sensing device (100) is touched, a first conductive layer (110) disposed on a supporting layer (115) is deflected toward a second conductive layer (120). The touch location is determined by sensing the change in capacitance at the location of the touch. A change in capacitance at the touch location is sensed by driving one of the conductive layers (110, 120) with an electrical signal referenced to the other conductive layer (120, 110) and measuring the current flow between the conductive layers (110, 120). The sensed change in capacitance is greater than a change in the external capacitance of the touch sensor.
