Pressure point detector
First Claim
1. A pressure point detector for detecting a location of a pressure point, comprising:
- a flexible insulation member in a predetermined shape;
a resistance film formed on one side of the flexible insulation member;
a conductive member made of conductive material and established to face the insulation member with a predetermined gap therebetween, anda pair of electrodes established on said resistance film in a parallel fashion to produce voltage distribution, thereby producing an output voltage from said conductive member indicative of a location of the pressure applied to the insulation member;
wherein the resistance film contacts the conductive member at a location corresponding to the point where the pressure is applied, and said pair of electrodes are formed in a radial direction on the resistance film from about a center of the resistance film, thereby differentiating voltages in a circular direction on the resistance film.

Abstract
A pressure point detector has a simple structure and is capable of detecting which location of a two-dimensional surface such as a circle a pressure is applied can be detected. The pressure point detector includes a flexible insulation member in a predetermined shape, a resistance film formed on one side of the flexible insulation member, a conductive member made of conductive material and established to face the insulation member with a with a predetermined gap therebetween, and a pair of electrodes established on the resistance film in a parallel fashion to produce voltage distribution. The pressure point detector produces an output voltage from the conductive member indicative of a location of the pressure applied to the insulation member.
