Abstract

See full text

A variety of applications can include apparatus and/or methods that provide an axial force transducer. Two coils wound coaxially with respect to each other can be used with a magnet to determine a distance traveled based on application of an axial force to an instrument component. The two coils and magnet can be configured in a number of ways with respect to the instrument component. In various embodiments, the difference between an inductance associated with one of the two coils along with its relation to the magnet and an inductance associated with the other one of the two coils along with its relation to the magnet can be used to determine the axial force on the component of the instrument associated with the distance travelled. Additional apparatus, systems, and methods are disclosed.
