Abstract

A fluidic tactile sensor includes a core having an outer surface, channels formed within the core, and an elastic skin disposed over a surface portion of the outer surface. Cells are formed between the surface portion and the elastic skin. Each cell is connected to one of the channels through an opening of the channel on the surface portion. Compressible fluid volumes extend between the elastic skin and the core. Each compressible fluid volume includes a first fluid volume formed inside one of the cells and a second fluid volume formed inside the channel connected to the one of the cells. The first and second fluid volumes contain portions of a continuous compressible fluid medium. A contact force applied to the elastic skin at a location corresponding to a given cell produces a measurable change in a fluid pressure of the continuous compressible fluid medium associated with the given cell.
