Paper Abstract

Over time, a wide variety of Haptic actuator have been designed and implemented to apply for mobile devices. This paper addresses an electrostatic actuator composed of an active film and patterned polydimethylsiloxane (PDMS) columns. A cellulose acetate (CA) film charged with an electric potential can generate vibration under the potential. The motion of the actuator is a concave and the actuator performance was modulated by increasing the bias level of the electric potential. The performance was evaluated depending on various actuation conditions in terms of electrical potential, bias voltage and frequency. It was found that the induced displacement of the actuator is proportional to the bias level of electric potential. Fast rising and falling behavior of the proposed haptic actuator can allow the generation of a vibrotactile sensation over a wide frequency range. The CA haptic actuator has a potential to generate a wide variety of tactile sensations.
