| Research Abstract |
A new technique for vector tactile sensing with MEMS devices was proposed. While tactile vectors had been conventionally measured with a combination of plural sensor elements each of which detected force in only one direction, the proposed technique enabled a single sensor element to measure a tactile vector based on resonant frequency shift of a vibratory microcantilever. The principle was confirmed in finite element analysis and the cantilever sensors were fabricated and evaluated. It was found that nonlinearity in the frequency response of the sensors drastically affected the tactile vector estimation, and an improved sensor structure to reduce the nonlinearity was designed and fabricated.
