Journal of Civil Structural Health Monitoring, 2020
A simple sensor design to achieve different electromechanical impedance (EMI) characteristics is required for the serial/parallel multi-sensing interrogation. Aiming at the shortcomings of traditional trial-and-error method for collocating serial/parallel PZT transducer with different EMI characteristics, this paper proposes a simple but effective ...

Ultrasonics, 2021
Ultrasound based Structural Health Monitoring (SHM) commonly uses surface-bonded piezoelectric wafer active transducers (PWaTs) for ultrasound wave generation and sensing. Both the electromechanical impedance (EMI) of the surface bonded PWaT and the ultrasound pitch-catch signal have been studied extensively for damage detection.

Abstract It is critical to develop an accurate non-destructive testing (NDT) methods to evaluate the real-time concrete strength gain due to the fast pace of construction. Among the NDTs for concrete strength monitoring, piezoelectric materials based electromechanical impedance (EMI) method has attracted much attention recently.

2021 3rd International Symposium on Signal Processing Systems (SSPS), 2021
The Structural Health Monitoring (SHM) of concrete structures, including fiber concrete structures, receives increasing attention, and the Electromechanical Impedance (EMI)-based method is commonly used. The aim of using fiber reinforced concrete is to maintain the distress in small cracks regarding their width and range.
