Based on a Chain Scattering Description and the Hilbert Huang Transform, this paper proposes a new measurement for monitoring dynamic changes of mechanical impedance without applying conventionally mechanical sensors. The proposed method is applied to the bone drilling system to detect the moment of bone breakthrough. The single frequency mechanical impedance of bone can be computed from the electrical signal of a DC motor in accordance with the proposed method. The experimental results demonstrate that the moment of bone breakthrough can accurately be detected by monitoring changes of mechanical impedance.
