Patent ID: 7197940

Claim:
A force measuring cell comprising: a deformable body and at least one strain gauge installed on the deformable body, wherein the at least one strain gauge has a strain-sensitive electrical resistor track and connector electrodes for contacting the resistor track arranged on a carrier substrate; wherein the at least one strain gauge and a part of the deformable body are provided with a multilayered coating composed of an alternating sequence of a polymer layer and a barrier layer, wherein the multilayered coating is formed of at least three thin individual layers, each of which was produced during a deposition process to adhere to its respective underlying surface, wherein a polymer layer forms a boundary layer to the strain gauge and to the part of the deformable body that is covered by the multilayered coating; and wherein the polymer layer performs a smoothing function of surface roughness of an area to be coated and covers edges and surfaces that are perpendicular to a plane of the polymer layer.
