LVDTs may not be new. But frictionless measurement and nearly infinite resolution never go out of style.

A linear-variable-differential transformer, or LVDT, is basically a transducer that converts mechanical motion into an electrical signal through mutual induction. A typical two-element LVDT consists of a fixed frame containing primary and secondary coils, and a movable core. The frame usually contains one primary winding sandwiched between the two secondary windings. ...
