  • Patent number: 9383848
    Abstract: A piezoelectric tactile input device and method in a computing environment. An embodiment disclosed herein includes a touch screen having several piezoelectric regions within a piezoelectric material layer that may generate a voltage when deformed in a localized area. The piezoelectric layer may be disposed between sensor layers of rows and columns of sensor traces for detecting the voltage generated at any particular piezoelectric region. The detected voltage signals may then be used to extrapolate the position of the localized area in which the piezoelectric layer was deformed (e.g., from a finger touch or a stylus). Further, because the piezoelectric layer generates a greater voltage in the presence of a greater pressure, the device may further decipher a relative level of force for the tactile input on the touch screen and detect multiple touch locations.
