Abstract:
Devices and methods are provided that facilitate improved input device performance. Specifically, the devices and methods facilitate input using a pressure-sensitive layer whose electrical admittivity changes in response to pressure applied to a touch surface. An input device is provided that comprises a plurality of sensor electrodes including a set of primary sensor electrodes and a set of secondary sensor electrodes. Each primary sensor electrode is electrically coupled to at least one secondary sensor electrode to form a set of electrical admittances. In one embodiment, the pressure-sensitive layer is located between the sensor electrodes and the touch surface, such that changes in the admittivity of the pressure-sensitive layer in response to pressure on the touch surface cause corresponding changes in the admittances between the primary and secondary sensor electrodes.
