Abstract
A device is disclosed for measuring the areal distribution of compressive forces which act substantially vertically with respect to a deformable measuring surface. A matrix arrangement of force sensors is provided, each of which is formed as a capacitance at crossings of substantially perpendicular conductor paths. The conductor paths are fixed on the opposed surfaces of an elastically deformable area-type dielectric and adapted to be connected by conductive elements to evaluator electronics. The conductor paths are printed on plastic substrate films.
