A method of force measurement, comprising: providing a dynamic inductance force transducer comprising a variable inductor including an induction coil having a wire configured as a plurality of turns with a hollow center having an inner opening that an inner core within can move in and out responsive to an applied pulling force to change its inductance depending on a magnitude of said pulling force, said force transducer including a spring having an end secured to a fixture and an opposite end secured to a first end of said inner core that has a second end opposite said first end having a coupling feature coupled thereto for attaching a load which provides said pulling force, characterized in that said inner core comprises a non-magnetic material that has a termina electrically coupled through said non-magnetic material to a contactor of the inner core positioned to electrically contact an inside surface of said wire of said induction coil so that said number of effective ones of said turns of said inductor coil changes with said pulling force due to movement of said contactor, which changes said inductance of said variable inductor; attaching said load to said coupling feature; connecting terminals of said variable inductor to first and second nodes of an oscillator circuit portion (220 or 220') to provide an oscillator circuit; measuring a signal at an output of said oscillator circuit to determine an oscillation frequency or a change in said oscillation frequency, wherein said pulling force from said load changes said inductance of said variable inductor which changes said oscillation frequency of said oscillator circuit, and determining a magnitude of said pulling force from said oscillation frequency or a pulling force change from said frequency change. providing a dynamic inductance force transducer comprising a variable inductor including an induction coil having a wire configured as a plurality of turns with a hollow center having an inner opening that an inner core within can move in and out responsive to an applied pulling force to change its inductance depending on a magnitude of said pulling force, said force transducer including a spring having an end secured to a fixture and an opposite end secured to a first end of said inner core that has a second end opposite said first end having a coupling feature coupled thereto for attaching a load which provides said pulling force, characterized in that said inner core comprises a non-magnetic material that has a termina electrically coupled through said non-magnetic material to a contactor of the inner core positioned to electrically contact an inside surface of said wire of said induction coil so that said number of effective ones of said turns of said inductor coil changes with said pulling force due to movement of said contactor, which changes said inductance of said variable inductor; attaching said load to said coupling feature; connecting terminals of said variable inductor to first and second nodes of an oscillator circuit portion (220 or 220') to provide an oscillator circuit; measuring a signal at an output of said oscillator circuit to determine an oscillation frequency or a change in said oscillation frequency, wherein said pulling force from said load changes said inductance of said variable inductor which changes said oscillation frequency of said oscillator circuit, and determining a magnitude of said pulling force from said oscillation frequency or a pulling force change from said frequency change.
