Handheld Medical Eddy Current Induction Damping Sensor

A method of manufacturing a handheld inductive sensor for body diagnostics, the method comprising:

• providing an electrical coil;
• connecting a resistive, inductive, and capacitive (RLC) circuit electrically with the coil;
• electrically connecting a frequency counter with the RLC circuit;
• rigidly connecting an inertial measurement unit (IMU) with the coil;
• and
• operatively connecting a computer processor with a machine-readable non-transitory medium embodying information indicative of instructions for causing the computer processor to perform operations comprising:
• generating a measured value based on an output from the frequency counter;
• calculating a position and an orientation of the coil with respect to a body part of a subject based on output from the IMU;
• and
• associating the position and the orientation with the measured value.
