Lifetime of wireless sensor nodes is a big challenge in bridge structural monitoring as these nodes may be deployed inside the bridges. In this situation, it is infeasible to replace batteries or harvest solar and wind energy. To prolong lifetime, vibration energy begins to be utilized to replenish energy for sensor nodes. In this study, a vibration energy harvester based on Micro Fiber Composite...
Cyber-physical-system (CPS) has been widely used in both civil and military applications. Wireless sensor network (WSN) as the part and parcel of CPS faces energy problem because sensors are battery powered, which results in limited lifetime of the network. To address this energy problem, we take advantage of energy harvesting device (EHD) and study how to indefinitely prolong oil pipeline monitoring...
