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.

Electromechanical impedance (EMI) measurements to infer features from the grinding process
International Journal of Advanced Manufacturing Technology, 2019 This paper discusses the correlations between the electromechanical impedance (EMI) technique and grinding parameters. The EMI technique applied in grinding is novel and has the advantage of employing cheaper equipment and requiring a simpler monitoring system when compared to traditional techniques, such as acoustic emission.

Electromechanical impedance (EMI) technique as alternative to monitor workpiece surface damages after the grinding operation [PDF]
International Journal of Advanced Manufacturing Technology, 2018 Electromechanical impedance (EMI) technique has been employed in detection of structural failure in civil and mechanical structures because of its non-destructive property and easy implementation of small and inexpensive piezoelectric transducers that are attached to the structures, which lead to cost reduction as well as lesser dependence of manual ...

Construction and Building Materials, 2020
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.
