Extracting local resonances using the electromechanical impedance method
ASNT Research Symposium 2023 Proceedings, 2023Local resonances, formed by zero-group velocity (ZGV) and cutoff frequency points, have been extensively studied using impulse induced by pulsed lasers and impacts. In this work, we demonstrated the effectiveness of the electromechanical impedance (EMI) technique in extracting ZGV and cutoff frequency resonance in a rectangular aluminum bar.

Electromechanical impedance method to assess dental implant stability
Smart Materials and Structures, 2012The stability of a dental implant is a prerequisite for supporting a load-bearing prosthesis and establishment of a functional bone?implant system. Reliable and noninvasive methods able to assess the bone interface of dental and orthopedic implants (osseointegration) are increasingly demanded for clinical diagnosis and direct prognosis.
