Abstract:
A haptic-enabled user interface device comprising a user input component, an elastomer suspension, a signal generating circuit, a signal sensing circuit, one or more switches, and a control unit is presented. The elastomer suspension is formed by at least one stack that includes an elastomeric layer, wherein the at least one stack forms at least one capacitor. The control unit is configured, in an actuation mode, to cause the one or more switches to electrically connect the signal generating circuit to the at least one capacitor and to electrically disconnect the signal sensing circuit from at least one capacitor, and to cause the signal generating circuit to apply a drive signal to the at least one capacitor. The control unit is further configured, in a sensing mode, to cause the one or more switches to electrically connect the signal sensing circuit to the at least one capacitor.

Claim (Index 38):
A haptic-enabled user interface device, comprising:\n a user input component; a base for supporting the user input component; an elastomer suspension for suspending the user input component on the base, such that the user input component does not directly contact the base, wherein the elastomer suspension is formed by at least one stack that includes a piezoelectric layer of piezoelectric material, a pair of electrodes on opposite sides of the piezoelectric material, and an elastomeric layer of elastomer material in contact with at least one of the pair of electrodes; a signal generating circuit; a signal sensing circuit; and a control unit in communication with the signal generating circuit and the signal sensing circuit, wherein the control unit is configured,\n in an actuation mode, to cause the signal generating circuit to generate a first signal as a drive signal that causes the piezoelectric layer to vibrate, \n in a sensing mode, to determine, based on a second signal sensed by the signal sensing circuit, whether a user input has been received by the haptic-enabled user interface device, wherein the second signal is caused by deformation of the piezoelectric layer.
