Abstract

A surface acoustic wave (SAW) tactile display consisted of a piezoelectric substrate and a slider. Rubbing the substrate through the slider, we could feel tactile sensations under a control depending on the rubbing motion. On the other hand, the piezoelectric substrate had constraint of size and shape. In this research, to solve this issue, a method was proposed to excite and propagate a SAW on a non-piezoelectric material surface. The method was realized by combination of a LiNbO₃ plate and a glass substrate. Characteristics were measured. The effectiveness of the proposed method for the tactile display was discussed. An active type SAW tactile display using the glass transducer worked successfully.
