Abstract:
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 material whose specific resistance ranges from 102 to 106 (&OHgr;Â·cm), 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 material whose specific resistance ranges from 102 to 106 (&OHgr;Â·cm), 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 adhesive member is formed at a position spaced apart from the first and second resistive elements so as to surround the first and second resistive elements, wherein the first contact portion and the second contact portion has a summed thickness that is larger than a thickness of the adhesive member, wherein at least one of the first and second substrates is flexible, wherein the first and second resistive elements are formed by screen printing, wherein the first and second resistive elements are constantly maintained in an electrical contact state, and an electrical resistance value measured between the first contact portion and the second contact portion is applied as a limited value, 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.
