Abstract :
We propose a novel method to provide human tactile sensation using surface acoustic wave (SAW). A pulse modulated driving voltage excites temporal distribution of shear force or friction shift on the surface of SAW substrates. The force/friction distribution can be perceived as tactile sensation at mechanoreceptors in the finger skin. A first prototype could express roughness successfully
