Abstract:
A weight sensor for measuring a weight applied to the sensor, comprising:a) a substrate including: 1) a center section that is adapted to flex in response to the applied weight; 2) at least one step section attached to the center section, the center section located adjacent the step section, the step section adapted to concentrate the weight applied thereon onto to the center section; and 3) at least one outer section attached to the step section; b) at least one strain gage resistor, mounted on the center section of the substrate, for generating an electrical signal in response to the substrate being stressed; and c) at least one wing section attached to the center section, the wing section adapted to be out of the path of the weight and not to flex, the wing section containing signal conditioning electronics operative to condition the electrical signal.
