【 摘 要 】

Wireless Sensor network (WSN) has received immense public interest in recent years. Due to ease of installation, optimum size, prolonged life and low cost, Wireless sensors Network (WSN) are widely used for Bridge health monitoring system. The solitary concern of such sorts of systems is the inadequate life of batteries that deliver power to them. In order to overwhelm this problem, energy harvester is an enduring solution. Energy harvesting is essentially seizure free energy from external sources and converts it to useable electrical energy. This paper reviews the supreme topical development of the energy harvesters in the field of structural monitoring system based on vibrations. The PE-VEHs and EM-VEHs are characterized based on their power production capability, resonant frequency, size, power density, base excitation and internal resistance etc. The overall power production range for the developed bridge energy harvesters is from 0.000016 to 31500 μW, conversely, the resonant frequencies of these energy harvesters lying in the range of 1Hz to 13.9 kHz. The power rank produced by the reported PE-VEHs fall in the range of 0.038 to 7700μW and their resonant frequencies are in the varying from 1Hz to 13.9 kHz. The developed EM-VEHs have comparatively low resonant frequencies ranges from (1Hz to 348Hz) and presented the competence of generating power from 0.000016 μW to 31500 μW.
