We have already proposed a novel method to provide human tactile sensation using surface acoustic wave (SAW). A pulse modulated driving voltage excites temporal distribution of standing SAW. The distribution generates friction shift on the surface of a SAW substrate. When the surface with burst SAW is explored, the friction shift can be perceived as tactile sensation at mechanoreceptors in the finger...
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...
A method to provide human tactile sensation using surface acoustic wave (SAW) was proposed. A stator transducer material (piezoelectric material) of a SAW tactile display, however, had constraint of size and shape. In this research, to solve this problem, a new method has been proposed to excite and propagate SAW on a non-piezoelectric material surface. Excitation and propagation of SAW on a non-piezoelectric...
