A WZ chip is structurally simple: a small chip with integrated capacitors and resonant circuits, applied via a thin adhesive film directly to the material surface.
Once applied, an electromagnetic interaction begins at the contact surface. This reorders free electrons in the material and, through a field-effect-like mechanism, locally shifts the elastic modulus.
That shift behaves like a change in the component’s natural frequency, similar to an eddy current brake: when the material is set in motion by external forces, additional magnetic fields are generated that oppose the motion and reduce the vibration amplitude — with no added mass or mechanical components.
