Compact force transducer with mechanical motion amplification

Abstract From the Canadian patent

Abstract of the Disclosure, A compact force transducer has at least one flexible beam mounted at one or both its ends to a force summing member or members. The force-to-be-measured is applied to the force summing member along a first axis generally transverse to the beams to deform the beam elastically, without overstressing through a displacement d. A sensor member carries a conductive surface and is coupled to the beam member. In a parallelogram form, there are a parallel pair of beam members extending between two force summing members and a sensor member is secured to each beam member at or near its point of inflection. One sensor member includes multiple arms that sandwich the other …
