ABSTRACT:
An electrical weighing scale for measuring the weight of a user having has a substantially transparent platform, a plurality of supports, and a display assembly. Piezoresistive sensors, disposed in the supports, change resistance in response to a change in the weight applied to the scale. The piezoresistive sensors include piezoresistive elements arranged in a half bridge structure that has been calibrated to provide zero balance, span matching and impedance normalization. The sensors are coupled in parallel to a display. The parallel arrangements produces a composite output signal that enables any number of sensors to be used in the scales design.
