<p>A method of adjusting the relative sensitivities of sections of a weighing mat which preferably includes three elastomeric, conductive layers. The outer conductive layers are separated from the central conductive layer by two, dielectric elastomeric layers having spaced ribs to form a capacitor whose capacitance varies with compressive loading. Due to different boundary conditions or manufacturing variations, sections of the mat have different relative sensitivities to an applied load. The method comprises removing from a mat section of low sensitivity at least one portion of one conductive layer to bring the relative sensitivities of the mat sections within predetermined tolerance limits.</p> |
