Abstract :
A tactile sensor has been developed which provides a 256-element tactile image to a host computer. The sensor contains all required circuitry to scan the sensor array and provide eight-bit digitized data as well as synchronization signals. The sensing area is 0.5 in.×0.5 in., providing spatial resolution of 0.031 in. The overall package measures 0.8 in.×0.8 in.×0.25 in., making it small enough to be located on a fingertip. The circuitry is located inside the package on a hybrid microcircuit which measures 0.5 in.×0.5 in. The sensing elements are force-sensing resistors with a wide usable force range
