Pressure-sensitive sensor

摘要

The present invention aims at providing a pressure-sensitive sensor capable of layering a pressure-sensitive layer and electrodes with high productivity, facilitating control of contact between the pressure-sensitive layer and the electrodes by loading, achieving good reproducibility of a resistance value generated by loading between the pressure-sensitive ink layer and the electrodes, and measuring pressure with high accuracy. The pressure-sensitive sensor comprises a pair of electrodes 16a and 16b formed on a substrate film 31, and a pressure-sensitive ink layer 30 juxtaposed to the electrodes on the substrate, the pressure-sensitive ink layer being variable in electrical properties in response to an applied pressing force, wherein a portion of the substrate film 31 having the pressure-sensitive ink layer 30 formed thereon is bent inward to allow the pressure-sensitive ink layer 30 to come into contact with the pair of electrodes 16a and 16b.

主权项

1. A pressure-sensitive sensor comprising,
a substrate having a rectangular portion and projecting portions which project from peripheries of the rectangular portion in the form of a trapezoid or a rectangle; a pair of electrodes formed on the rectangular portion along the peripheries of the rectangular portion; and a pressure-sensitive ink layer formed on the projecting portions, the pressure-sensitive ink layer being variable in electrical properties in response to an applied pressing force, wherein the projecting portions are bent inward to allow the pressure-sensitive ink layer to come into contact with the pair of electrodes.
