Patent number: 10558269Abstract: A device for providing cutaneous sensations to a fingertip includes a lower base, an upper platform positioned over and mechanically connected to the lower base, and a shear plate positioned between the lower base and the upper platform and mechanically connected to the lower base. When a fingertip is positioned between the upper platform and the lower base, the upper platform is selectively vertically translatable relative to the lower base to provide a compressive force, and the shear plate is selectively laterally translatable relative to the lower base to provide a shear force. Accordingly, a wearable fingertip device having two degrees-of-freedom (DoF) to provide consecutive and/or concurrent compressive force and/or shear force to a fingertip is provided. The wearable fingertip device can be used in various scenarios; is portable, easily wearable, and easily manufacturable; and has low overall operating power requirements.Type: GrantFiled: September 22, 2017Date of Patent: February 11, 2020Assignees: ARIZONA BOARD OF REGENTS ON BEHALF OF ARIZONA STATE UNIVERSITY, STC.UNMInventors: Marco Santello, Francesco Chinello, Daisuke Shibata, Domenico Prattichizzo
