Abstract

A smart mechanical component has a mechanical part main body; a mechanical part secondary body located inside of the mechanical part main body; a three dimensional three-dimensional (3-D) reserved space located between the mechanical part main body and the mechanical part secondary body; at least one connecting unit connecting the mechanical part main body and the mechanical part secondary body; wherein the mechanical part main body, the mechanical part secondary body and the three dimensional three-dimensional (3-D) reserved space form a capacitor; the connecting unit forms an inductor; the inductor and the capacitor forms an inductor-capacitor circuit.

Claims

1. A smart mechanical component, comprising:

a main body, wherein the main body is a screw or a hook;

a secondary body, wherein the secondary body is an inner shaft furnished in the main body, and the main body is not in contact with the secondary body;

a three-dimensional (3-D) reserved space, positioned between the main body and the secondary body; and

an inductor bridged between the main body and the secondary body and located adjacent to a head part of the main body, wherein the inductor has a spiral shape, a center end of the inductor connects to an end of the inner shaft, and a spiral end of the inductor connects to the screw or the hook, for connecting the main body and the secondary body;

wherein, the main body, the secondary body and the three-dimensional (3-D) reserved space form a capacitor, and the inductor and the capacitor to form an inductor-capacitor (LC) circuit; and
