Abstract

In order to investigate tactile perception characteristics of the human fingerpad for optimal designs of sensory substitution devices, we developed a small piezoelectric bimorph actuator whose frequency characteristics were kept flat in tactilely perceivable frequency range. The parameters for the design of the bimorph were determined by using a mechanical simulation model of the piezoelectric bimorph and the finger skin. To evaluate the performance of the bimorph, we measured frequency-displacement relationships when the fingerpad was vibrated by the piezoelectric bimorph. The experimental results showed that the frequency-displacement relationships were almost the same as the estimation obtained from the mechanical simulation model. The developed bimorph should be able to generate various but precise skin displacement patterns onto a fingerpad in accordance with the wave form of the input voltage to the bimorph.
