Abstract:
1. A flexible force or pressure sensor array using semiconductor strain gauges, the sensor array comprising: a substrate including: the semiconductor strain gauge array in which a plurality of elements formed in a certain pattern is deformed by force or pressure, a pair of polymer film layers having film surfaces contacted facing each other and containing the semiconductor strain gauge between the film surfaces contacted with each other, and a pair of signal line layers formed on top and bottom surfaces of an insulating layer using either of the pair of polymer film layers as the insulating layer and connected to the elements of the array pattern to form electrodes, for fetching deformation signals outputted due to deformation of the elements to outside; and a pair of elastomer layers formed on both sides of the substrate to contain the substrate inside, wherein the pair of signal line layers includes a plurality of first signal lines arranged in one direction on one surface of the insulating layer and a plurality of second signal lines arranged to be perpendicular to the one direction, and resistance of the elements is changed based on the force or the pressure and the deformation signals are outputted based on the changes of resistance.
