ELECTRONIC PRESSURE-SENSITIVE DEVICE FOR DETECTING THE MAGNITUDE OF LOAD AS ELECTRICAL RESISTANCE
First Claim
1. An electronic pressure-sensitive device comprising a first substrate consisting of an insulating material, a first contact portion formed on the first substrate, a first resistive element consisting of a high-resistance material, constituting the first contact portion and provided on the outermost surface of the first contact portion, a second substrate consisting of an insulating material and opposed to the first substrate, a second contact portion formed on the second substrate and opposed to the first contact portion, a second resistive element consisting of a high-resistance material, constituting the second contact portion and provided on the outermost surface of the second contact portion, and an adhesive member provided between the first and second substrates and gluing the first and second substrates to each other, wherein the first and second resistive elements are constantly maintained in an electrical contact state, and wherein a press contact force acting between the first and second resistive elements by pressurizing the first and second contact portions;
- from at least one side is detected as the electrical resistance between the first and second contact portions.

Abstract
Disclosed is an electronic pressure-sensitive device which has a long service life and which is capable of detecting with high accuracy loads of various magnitudes including values in proximity to zero. In the electronic pressure-sensitive device, first and second resistive element layers 2b and 6b are formed on the outermost surfaces of first and second contact portions 2 and 6, and the first and second resistive element layers 2b and 6b are constantly maintained in an electrical contact state, the force bringing the first and second resistive element layers 2b and 6b into press contact with each other being detected as the electrical resistance between the first and second contact portions 2 and 6.
