Abstract
A pressure sensitive sensor in which a pressure detecting convex portion is formed on the surface of a pressure-sensitive and conductive elastomer sheet, and an electrode is arranged on the reverse side of the pressure detecting convex portion for making it possible to detect a pressure acting in the direction in parallel or in the oblique direction with a slight angle with respect to the surface of a pressure-sensitive and conductive elastomer component. In addition, for obtaining a high detection density, a contact is made up with a face-defined body defining a pressure face, and a contacting convex portion is made to protrude from the face-defined body, where the contact is resiliently supported onto the pressure-sensitive elastomer sheet.
Claims8
A pressure-sensitive sensor comprising:
- a pressure-sensitive and conductive elastomer component;
- an electronic sensing means disposed at a first location on a front side of said pressure-sensitive and conductive elastomer component for sensing changes in the electrical resistance occurring in response to the deformation thereof;
- and
- a pressure sensing convex portion formed at a second location opposite the first location on a reverse side of said pressure-sensitive and conductive elastomer component, wherein
- said electronic sensing means comprises a plurality of electrodes arranged such that the direction of pressure exerted upon said convex portion in a plurality of directions relative to said surface of said pressure-sensitive and conductive component may be detected.
A pressure-sensitive sensor comprising:
- a contact including a face-defined body defining a pressure face and further a contacting convex portion made to protrude from said face-defined body;
- a pressure-sensitive and conductive elastomer component under pressure from the pressure face of said contact;
- an electronic sensing means connected to said contact through said pressure-sensitive and conductive elastomer component for sensing changes in the electrical resistance occurring in response to the deformation of said pressure-sensitive and conductive elastomer component,
- wherein said contact is shiftably supported against said pressure-sensitive and conductive elastomer component, and
- wherein the contacting convex portion of said contact is made to protrude outwardly of the surface of said pressure-sensitive and conductive elastomer component so that the direction of pressure exerted upon said contact in a plurality of directions relative to said surface of said pressure-sensitive and conductive component may be detected by said electronic sensing means.
