エレクトレットを用いた力覚機能を有する人工皮膚に関する研究

抄録

We propose an artificial skin with a flexible thin film and a tactile function that requires no external power supply. The proposed skin is made from a lamination of an electret, an elastomer and two electrodes. The electret is a material in which electric charges are stored semi-permanently. In this study, an electret with a thickness of 15 μm was made by applying amorphous fluororesin on a 10 μm thick copper electrode. After that, an elastomer containing carbon black was applyed to the opposite electrode with a thickness of 250 μm, and these were overlaid to produce an artificial skin of about 300 μm. These were laminated each other to produce an artificial skin. The results of experiments in which the pressure was applied to the prototype skin showed that the detected, voltage was 0.5V, which was sufficient to used as a sensor for detecting the contact.
