In this paper, we demonstrate encoding of a surface texture and displaying it to a subject using a MEMS-based tactile display. The tactile display is composed of a piezoelectric actuator array and hydraulic displacement amplification mechanism. We now use the display to encode, or copy, the surface texture by sliding the surface on the display. The obtained waveforms from the piezoelectric actuator array, which worked as the sensor array, was, in turn, amplified to drive the actuator arrays to display the surface texture to the subject whose fingertip was placed onto the display. We successfully copied the surface textures of samples and could even blend the surfaces to create new surfaces with various hardness and roughness. The proposed system is readily applicable to advanced human-computer interactions.
