Abstract :
Previously, a novel 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 is 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. Successful work of an active type SAW tactile display using the glass transducer is reported. Additionally, installation of the glass transducer on an LCD to indicate tactile sensation with visual information and its demonstration are described
