Touch feedback and sensing device
A touch feedback and sensing device includes a circuit board, a piezoelectric ceramic actuator on the circuit board; and at least one strain sensor on the circuit board. The piezoelectric ceramic actuator includes a piezoelectric ceramic block, a cathode and an anode on the piezoelectric ceramic block. Different voltages are applied to the cathode and the anode to vibrate the piezoelectric ceramic block. The circuit board vibrates with vibration of the piezoelectric ceramic block. The at least one strain sensor is configured to detect and monitor vibration of the circuit board.
