A Glass Substrate Transducer for Surface Acoustic Wave Tactile Display

We had proposed a novel method to provide human tactile sensation using surface acoustic wave (SAW). A pulse modulated driving voltage is applied to reproduce human tactile sensation. To expand its application, a glass substrate SAW transducer has been proposed. The glass substrate transducer worked successfully. In the application, however, user's rubbing motion was limited to one-dimensional motion. To expand tactile display application, a wide and long transducer would be required. Such a transducer can realize two-dimensional tactile display. To improve energy efficiency, a new design of the transducer was proposed. This paper describes design of the new glass substrate transducer and its fabrication. Characteristics of the transducer are also reported.
