Time-Domain Electromechanical Impedance for Structural Health Monitoring
(European Assoc Structural Dynamics, 2011-01-01)
Electromechanical impedance (EMI) technique is a very simple method that can be usefulness in most of Non-Destructive Evaluation (NDE) and Structural Health Monitoring (SHM) systems. A common application of EMI methods is ...

A New Impedance Measurement System for PZT-Based Structural Health Monitoring
(Institute of Electrical and Electronics Engineers (IEEE), 2009-10-01)
Recent research has shown that electromechanical (E/M) impedance-based techniques are an efficient strategy for damage sensing in the context of structural health monitoring (SHM). The basic principle is to excite the lead ...
New design of a variable impedance based on polarized diodes at microwave frequency
(Institute of Electrical and Electronics Engineers, 2017-05)
In this letter, we present a new variable impedance termination consisting of two polarized diodes. To generate a complex-valued impedance, two controlled current sources polarize the diodes, which are interconnected with ...
Time-domain analysis of piezoelectric impedance-based structural health monitoring using multilevel wavelet decomposition
(Academic Press Ltd Elsevier B.V. Ltd, 2011-07-01)
A new approach to analyze the response from a piezoelectric wafer in an impedance-based structural health monitoring (SHM) method is proposed. It is shown that the time-domain response of a piezoceramic wafer provides ...
Impedance-based structural health monitoring with artificial neural networks
(2000-03-01)
This paper presents a non-model based technique to detect, locate, and characterize structural damage by combining the impedance-based structural health monitoring technique with an artificial neural network. The impedance-based ...
