提出了一种利用声表面波（SAW）提供触觉的新方法。脉冲调制驱动电压激励驻波SAW的时间分布。该分布在SAW基片表面产生交替摩擦位移。当探索具有突发SAW的表面时，摩擦移位可以被感知为手指皮肤中的机械感受器处的触觉。我们分析了手指在粗糙表面上的滑动运动，并制作了一个原型，它可以成功地表达粗糙度。
We 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 alternative friction shift on the surface of SAW substrate. When the surface with burst SAW is explored, the friction shift can be perceived as tactile sensation at mechanoreceptors in the finger skin. We analyzed a sliding motion of a finger on a rough solid surface and fabricated a prototype, which could express roughness successfully.
