Abstract
In this paper, the novel tactile device considering nail function, the tactile nail chip, is discussed. Nails are not just the best instruments to scratch. They enhance fine touch, protect fingers, and improve our tactile sensitivity. Previously, we focused on the deformation of nails by nail polish and proposed the tactile nail chip affecting tactile sensation. In this paper, a prototype of the tactile nail chip is designed on the basis of the mechanism of nail deformation, and fundamental experiments using a soft rubber finger with a nail are done to discuss the effect of the tactile nail chip on our fingers and tactile sensation.
