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.
