Structural Health Monitoring (SHM)
The vast field of structural health monitoring (SHM) seeks to develop sensing techniques that can provide some measure of mechanical integrity or "health" of a structure. Just like a medical doctor inspects a patient, SHM can be used to get a health record for a structure such that damage can be detected, located, quantified, and even predicted. This is accomplished using a variety of methods including: electromechanical impedance, wave propagation, electrical resistance tomography, fiber optics, acoustic emission, and structural response. Research in SHM focuses not only on the sensor design, placement, and mechanisms, but also on data analysis, neural networks, and learning algorithms.
