Position sensor comprising elastomeric material
First Claim
1. A position sensor comprising:
- at least one body of an elastomeric material in the form of a sheet;
mounting means for mounting a first part of the body to a support;
movable means joined to a second part of the body at a distance from the first part, the movable means being movable to stretch a third part of the body located between the mounting means and the movable means;
opposed first and second outer surfaces provided on the third part;
a first electrode formed on the first surface; and
a second electrode formed on the second surface.

Abstract
The present invention relates to transducers for converting the spatial position of an object into an electrical signal, more specific to a novel position sensor which has advantages of simplicity, long-term stability and durability. According to the invention, a position sensor comprises at least one body of an elastomeric material, mounting means for mounting a first part of the body to a support, and movable means joined to a second part of the body at a distance from the first part, the movable means being movable to stretch a third part of the body located between the mounting means and the movable means. The sensor has opposed first and second surfaces on the third part, a first electrode on the first surface, and a second electrode on the second surface.
