ABSTRACT:
A pressure measurement device and a method for making it are disclosed. A plurality of thick-film resistors are screen-printed onto a deformable substrate, after which they are preferably fired. The resistors are then connected to circuitry for measuring changes in their respective resistances due to deformation of the substrate by an external force or pressure to be measured.
