Abstract :
A silicon-based shear-force sensitive sensor is developed for the study of human-object interfaces. The sensor is designed based on the piezoresistive effect in silicon and fabricated using microfabrication technology. Detailed characterization of sensor prototypes is performed (linearity, R>0.98; repeatability, STD<8%). Shear sensing ability is demonstrated. Preliminary results of human subject tests are also described
