Abstract
A tactile sensor unit is provided, which includes a substrate; a coat formed on the substrate; and a cantilever beam structure having one end fixed to the substrate and curved to rise in such a direction that the other end of the cantilever beam structure is farther from the substrate than the one end. The tactile sensor unit detects a load applied to the coat. The cantilever beam structure is capable of resonating at a first resonant frequency and a second resonant frequency which is different from the first resonant frequency. The tactile sensor unit further includes a computation section for calculating a directional component of the load based on a change ratio of the first resonant frequency obtained in accordance with a change in the load and a change ratio of the second resonant frequency obtained in accordance with the change in the load.
