摘要：
Surface acoustic waves (SAWs) excited by bursts of sinusoidal waves have been used in various applications. However, the SAW actuators used for this purpose are expensive because each SAW transducer must be equipped with a radio frequency linear amplifier and a function generator. To simplify the driving circuits of these actuators, SAW excitation using a pulse wave is proposed in this report. Simulated results for an equivalent circuit of a single interdigital transducer and measurements of SAWs excited by pulse waves are presented. The generation of tactile sensations using a SAW excited by a pulse wave is also reported. Furthermore, the power requirements for SAW excitation by a sinusoidal wave and by a pulse wave are compared. © 2016, Fuji Technology Press. All rights reseved.
