Wireless sensor networks for structural health monitoring
Summary
I have been conducting research on wireless sensor networks for structural health monitoring and currently I supervise three Ph.D. students working in the following two aspects.
(i) Geo-event sensing: we have investigated a novel wireless signal network that can function as a versatile sensor to characterize properties of subsurface geo-media and to monitor indiscriminate geo-events. The proposed network is based upon algorithmic evaluation of real-time link quality signals among distributed wireless transceivers. (ii) Bridge monitoring: we have designed a wireless sensor network capable of being preemptively triggered that can capture the critical dynamic response of a bridge during and after an earthquake, and that it can conduct distributed modal identification so that the agility of damage characterization and the efficiency of energy consumption of the bridge monitoring system can be improved.
