Abstract
Array haptic actuator to realize texture of button for virtue flight simulator is fabricated by using cellulose acetate (CA) film. The haptic actuator has independent 3 × 3 cells for identical vibration. Each cell consists of topside CA layer and bottomside CA layer with two pillars. Two ends of topside CA layer are fixed on the pillars similar with fixed end beam. By an electrostatic force in the presence of electric field, the topside CA layer vibrates. Each cell shows its resonance frequency peak in the capable frequency range of vibrotactile feeling from 100 Hz to 500 Hz. The acceleration performance is shown to be higher than vibrotactile threshold on wide frequency band from 100 Hz to 400 Hz.
