Development of microfluidic chip type electrostatic tactile display

Abstract

This paper reports a development of microfluidic chip type electrostatic tactile display. In our prior work, we fabricated thin electrostatic tactile display that can be attached to peltier device and we successfully presented surface roughness and thermal sensation at the same time. However, the texture feeling is limited to the presentation of the roughness feeling and three types of tactile impression, and it has not reached the complicated tactile presentation accompanying the deformation of the surface shape. Therefore, in this study, we propose a display that presents a more complicated texture feeling by pressing the liquid metal against the surface and changing the surface shape of the tactile display itself.
