Abstract
Our group demonstrated a MEMS-based tactile display that can control the created surface textures by the driving frequency and voltage of the actuators. It can create rough or smooth surfaces, but so far it is not successful to control the characteristics of the created surfaces that include roughness, hardness, etc. This paper attempted to obtain the actuation patterns of MEMS tactile display to create a designated surface textures. In order to do so, we slide the surface on the tactile display, consisting of an array of piezoelectric actuators, and detect the generated voltages by the actuators. The ultimate goal of this work is to code the surface textures into frequency and voltage.
