This paper proposes a new thin and flexible vibrotactile module based on an electroactive polymer with 3×3 actuating cells. Since all components of the proposed module are flexible, the proposed module can be easily embedded into commercial mice having any shape. An experiment is conducted to investigate that the proposed module can generate enough force to stimulate human's mechanoreceptors with...
Recently, nanocomposite materials have attracted much attention in electrical treeing. In this study, we carried out a three-dimensional (3D) tree simulation using two macrosized fillers (i.e., spherical and discoid) as the first step in considering simulated trees in nanocomposite materials. Moreover, we carried out a comparison of simulated tree shapes depending on filler type. The results indicate...
In this paper, a first prototype of a multifunctional tactile sensor using ionic polymer metal composites (IPMCs) is proposed, designed, and tested. Two IPMC strips are used, one as an actuator and one as a sensor, both positioned in a cantilever configuration; working together they enable the system to detect the presence of a material in contact with it and to measure its stiffness. These sensing...
