Abstract

Glass fibre composite, as a high strength and lightweight structural material, is widely applied to the wind turbine blades. Without affecting its mechanical properties, the vibration energy harvesting capability to power attached wireless sensor networks (WSNs) technology can be realized by integrating PZT macro- fibre composite onto the structure. Based on the multifunction composite concept, a PZT macro-fibre composite co-cured within the surface of glass/epoxy pre-preg is manufactured. The resultant mechanical plate combined with actual vibration data from wind field can implement power generation. The experiment average output voltage of 4.10 V, which relates to power of 0.84 mW, was estimated. The FEA simulation average output voltage is about 4.46 V, which the error is less than 10% compared with experiment.
