State-of-the-Art Wireless Acoustic Emission System for Structural Health Monitoring
In recent years, there has been an increasing demand for wireless operation and sensor fusion for structural health monitoring on aged infrastructures. Although advanced wireless and sensor fusion technologies have made it possible to develop equipment for such an application, there are some critical issues for such equipment to be effectively and reliably used in infrastructure sites. This paper addresses these critical issues and introduces solutions and state-of-the-art features implemented in a wireless AE system. Laboratory and field tests have been conducted to prove the necessity and effectiveness of the measures taken in the design of wireless AE systems.
