Understanding the effects of adhesive layer on the electromechanical impedance (EMI) of bonded piezoelectric wafer transducer

Smart Materials and Structures, 2014
This paper investigates the effects of the adhesive layer on the admittance of bonded piezoelectric wafer active sensors (PWASs) through mode identification, parametric studies, and experimental verification. Based on the time-frequency analysis of the broadband ultrasound pitch-catch signal, we discovered that the resonances of the PWAS actuator ...

Monitoring of crack repair in concrete using spherical smart aggregates based on electromechanical impedance (EMI) technique

Smart Materials and Structures
Abstract Cracks will inevitably occur in concrete structures or members during the construction process and service life due to aging, environmental factors, external loads, etc. To improve the strength and stability of the cracked concrete structures, many methods have been proposed to repair the cracks.
