Abstract

The mat is formed from two sheets (1, 2) of electrical conducting rubber. These two sheets of rubber are held apart from each other by an insulating sheet(3). The insulating sheet has perforations (31, 32) in it. A pair of electric wires (11, 21) are respectively connected to the conducting rubber sheets. The wires are connected to the input of a continuous current amplifier (4) associated with a relay (5). The supply to the relay and amplifier is from a direct current source. Under the effect of a force application in the direction of the arrow f the upper rubber sheet (1) is deformed and touches the lower sheet (2) through the perforations.
