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.
