Vibrotactile feedback is a key feature of many small touchscreen devices, but is often absent or incomplete in large touchscreen displays due to a lack of suitable actuators for such applications. Thus, a growing need exists for haptic actuators capable of producing meaningful feedback in large touch displays. This study proposes and evaluates a dual-electrode electrostatic resonant actuator (ERA) as a means to fulfill such a need. The dual-electrode ERA was compared to a similar singleelectrode ERA to study the effect of electrode configuration. It produced a maximum vibration 73% higher than the single-electrode actuator, showing promising potential for its use in large touchscreen applications. To study the ERA in a large display application, a prototype touch bar system with spring boundaries was designed, fabricated, and evaluated. By varying the number of actuators excited in the system, the actuators’ magnitude, excitation frequency, and signal duration, a maximum vibration of 4 g-forces could be achieved throughout the majority of the display in both sustained and pulse sensations. This demonstrates a promising potential for generating a freely positionable and fully controllable point of vibrotactile stimulation at any point of a touch bar display. These results show the feasibility of the actuator spring boundary implementation and the dual-electrode ERA for large touchscreen display applications.
