Measurement mat for laminar pressure distributions - has transverse and longitudinal conductors on either side forming electrodes

摘要

A pressure measurement transducer for laminar pressure distributions consists essentially of an elastic material, whose electrical conductivity increases under the effects of pressure and electrodes attached to either side of the material. It is simply constructed and enables measurement over large surfaces economically and with few connections. The elastic material is in the form of a mat (3) of size appropriate to the measurement surface. Two opposing electrodes are placed one on either side of the mat for each measurement point. The electrodes for each point of measurement consist of crossing points of conducting paths (1,2) running longitudinally on one side and transversally on the other. The thickness of the mat is between 0.1 and 5 mm., and pref. between 0.5 and 1 mm.
