Project description

The research team has successfully developed and implemented a nondestructive testing (NDT) method using piezoelectric sensors to measure real-time concrete strength and stiffness. However, the current hardware and software are bulky and inconvenient for field implements. This project will develop a wireless sensor with hand-held devices or portable terminals, and associated graphic interface, to make devices easy for field implementation.
