Abstract

A pressure sensor includes upper and lower conductive layers (1, 3) separated by an intermediate insulating layer (2) which is formed as a separating mesh. The upper conductive layer (1) is of negligible resistance. The lower conductive layer (3) is formed of a plurality of conductive strips (A-F) separated by insulating strips. Each conductive strip (A-F) has a known resistance. An electrical signal is applied to the conductive strips (A-F) in turn and the electrical path between the upper and lower conductive layers (1, 3) then determined. The electrical resistance of the conductive path establishes the location of the pressure point at which bridging occurs and from this it is possible to establish the location and size of the pressure area.
