我们提出了一种利用声表面波(SAW)来提供人类触觉的新方法。脉冲调制驱动电压激发了竖立声表面波的时间分布。这种分布在SAW基板表面产生摩擦位移。当探索带有爆裂锯的表面时，摩擦移动可以被感知为手指皮肤中机械感受器的触觉感觉。为了真实再现触觉，根据测量的摩擦运动来控制脉冲频率。讨论了控制参数及其设置方法。研究了触觉显示所需的参数及其调谐。
We have 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 skin. For real reproduction of tactile sensation, the burst frequency was controlled according to measured rubbing motion. We discussed the control parameters and their arrangement. Required parameters and their tuning for the tactile display were investigated.
