Abstract :
This paper reports on a shear force detector using piezo-resistive beams with sidewall doping embedded in elastic body. These beams are formed using a 20 μm-thick device Si layer of an SOI (Silicon on Insulator) wafer. Shear force is measured by the resistance change due to the extension/compression of the sidewall. The size of the beams is 180 μm × 15 μm × 20 μm (length × width × thickness). Using these shear force detectors, a triaxial tactile sensor can be fabricated.
