提出了一种利用表面声波（SAW）提供人类触觉的方法。然而，SAW触觉显示器的定子换能器材料（压电材料）具有尺寸和形状的限制。在本研究中，为了解决这个问题，提出了一种在非压电材料表面激发和传播声表面波的新方法。 SAW在非压电材料上的激发和传播是通过LiNbO3板和玻璃基板的组合来实现的。本文描述了大尺寸玻璃基板传感器的设计和制造，用于使用 SAW 指示触觉的新方法。该设计采用了先前提出的新颖的换能器结构。使用传感器，可以进行二维摩擦运动。本文还报告了受控滑块速度的测量结果。结果表明，基于作者提出的触觉显示原理，成功地显示了粗糙感。
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 material is realized by a combination of a LiNbO3 plate and a glass substrate. This paper describes design and fabrication of a large sized glass substrate transducer for the novel method to indicate tactile sensation using SAW. The design employs the novel transducer structure, which has been proposed previously. Using the transducer, two-dimensional rubbing motion is available. This paper also reports measurement result of speed of a slider under control. The result indicates successful display of roughness sensation based on the tactile display principle proposed by authors.
