Pressure-sensitive resistor sensor
First Claim
1. 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 extending in a first direction, and wherein the second electrode layer is formed with at least one second electrode portion that is arranged in a transverse relation with a plural of the first electrodes.

Abstract
It is the objective of this invention to reduce deviation in contact resistance variation between electrodes among pressure-sensitive resistor sensors. The sensor is composed of a pair of films. One film has a plurality of electrode portions extending in a certain direction and the other film has at least one electrode portion that is arranged in a transverse relation with a plural of the electrode portions on the other film. Contact points generated by applied pressure are limited to crossing points between the electrode portions of the pair of films. As a result, variation in contact resistance due to applied pressure shift becomes more constant. Thus, it is possible to reduce deviation of contact resistance between the electrodes among sensors.
