Abstract:In this paper, the design and simulation of a tactile display that is based on a capacitive micromachined ultrasonic transducer (CMUT) array is presented. The array implements a 'pixel' of the display and is used to focus airborne ultrasound energy on the skin surface. The pressure field generated by the focused ultrasound waves excites the mechanoreceptors under the skin and transmits tactile information. The geometry of the individual transducer and the array are optimized so that the medium presents maximum… Show more
