Pressure distribution sensing device

Abstract

The present disclosure relates to devices for measuring a pressure distribution, also referred to as a pressure mapping device or pressure sensor mat, and to a method of manufacturing. The device comprises: a first and a second flexible substrate, a spacer structure extending between the substrates and a plurality of force-sensitive sensor nodes. Each sensor node comprises a first conductive element attached to first substrate and a second conductive element attached to the second substrate facing the first conductive element, the first conductive element being movable in use in relation to the second conductive element to vary the resistance of the force-sensitive sensor node. The spacer structure comprises a plurality of isolated spacer elements distributed between adjacent sensor nodes, and wherein spacings between adjacent ones of the spacer elements provide an interconnected network of gas passages between the sensor nodes.
