Energy harvesting for a self-powered compact Structural Health Monitoring system based on Acoustic Emission
The use of composite materials in aerospace structures has been recently increasing on the basis that they could make structures lighter whilst maintaining the same level of safety; concerns and uncertainties on damage behaviour of such materials, especially on their tolerance to impacts, have forced designers to increase safety factors to a point that the use of advanced lightweight composite ...
متن کاملDeveloping a Self-Powered, Wireless Damage Detection System for Structural Health Monitoring Applications
The research presented in this manuscript introduces an independent structural health monitoring (SHM) system capable of performing impedance-based testing and detecting shifts in resonant frequencies. This independent structural health monitoring system incorporates a low power wireless transmitter that sends a warning signal when damage is detected in a structure. Two damage detection techniq...
متن کاملStructural health monitoring using piezoelectric impedance measurements.
This paper presents an overview and recent advances in impedance-based structural health monitoring. The basic principle behind this technique is to apply high-frequency structural excitations (typically greater than 30kHz) through surface-bonded piezoelectric transducers, and measure the impedance of structures by monitoring the current and voltage applied to the piezoelectric transducers. Cha...

متن کاملTitle: Structural Health Monitoring with Piezoelectric Wafer Active Sensors
Piezoelectric wafer active sensors (PWAS) are inexpensive, non-intrusive un-obtrusive devices that can be surface-mounted on existing structures, or inserted in a new composite structure. The PWAS can be used in both active and passive modes. In active mode, the PWAS generate Lamb waves that can exist as either traveling waves or standing waves. As traveling waves, PWAS-generated Lamb waves can...
