摘要： A force sensor for measuring force and/or torque about a single axis or multiple axes is rugged, inexpensive and can be fabricated over a wide range of sizes. The force sensor includes first and second members that are coupled to each other by an elastomeric flexure that allows at least one member to be movable with respect to the other member when a force is applied. The force sensor includes a transmitting coil or printed circuit trace and a receiving coil or printed circuit trace. In one embodiment, the transmitting and receiving coils are formed on different ones of the first and second members. In another embodiment, the transmitting and receiving coils are formed on the same member and the other member is formed as a shading plate. A signal applied to the transmitting coil induces a signal in the receiving coil that represents the force applied.
