Abstract:
A pressure-sensitive resistor sensor comprising:a first film having a first electrode layer; and a second film having a second electrode layer, the second electrode layer being spaced apart from the first electrode layer by a predetermined distance and facing the first electrode layer, wherein the first electrode layer is formed with a plurality of first electrode portions including a plurality of positive side electrode portions arranged in parallel with each other in a comb-shaped configuration and a plurality of negative side electrode portions arranged in parallel with each other in a comb-shaped configuration, the positive side electrode portions and the negative side electrode portions being interleaved with one another with a predetermined clearance defined therebetween; the second electrode layer being formed with a plurality of concentrically arranged second electrode portions; each of the positive side electrode portions and each of the negative side electrode portions respectively cross over any one of the plurality of second electrode portions to form a plurality of crossing points; and the second electrode portions are arranged to electrically contact the positive side electrode portions and the negative side electrode portions upon application of pressure thereto to short the positive side electrode portions and negative side electrode portions.
