ABSTRACT:
A force sensor, or a method, determines a force using at least a measured inductance in a coil wherein a quantum tunneling composite is located in a magnetic path created by the coil, is positioned in a load path of the force, and is under strain from the force. A strain sensor, or a method, determines a strain using at least a measured inductance in a coil wherein a quantum tunneling composite is located in a magnetic path created by the coil, is positioned in a load path of a force, and is under strain from the force.
