摘要
Background, Motivation and Objective Energy is the material foundation of human existence and economic development. With the rapid development of economy, however, energy shortages, environment pollution and ecologic deterioration has become increasingly serious. Thus the invention and manufacture of more environmentally friendly equipment are of greats importance to researchers from all over the world. Wind energy in the ambient can be harvested as a new type of energy since which exists in almost every corner of the natural world. For low-power electronic devices, if its battery is equipped with small charging system getting energy from the surrounding environment, the battery replacement will be greatly reduced. It is one possible solution that the surrounding wind energy converted into electrical energy by piezoelectric materials. Our aim is to design an environmentally friendly, efficient and simple, easily to manufacture, low cost wind energy collection device, which can supply the power for the low-power wireless sensor networks and so on. Statement of Contribution/Methods This work used the PVDF piezoelectric film as an energy conversion material to design an efficient wind energy collection equipment which has simple structure, low cost and high efficiency. This device transforms random wind energy into electrical energy by an effective vibration action of the piezoelectric film. The simulation of the swing state of PVDF in the device by the software ANSYS. The PVDF piezoelectric film in series and parallel are both analyzed to investigate the effect of the wind speed and pressure on output voltage and power. For the sake of comparison, an experiment is conducted to evaluate the effect of the wind speeds on the PVDF piezoelectric film using a fan to simulating the natural wind. Results This paper shows that the force on the piezoelectric film increases with the increase of the wind speed because the greater distortion of the PVDF piezoelectric film creates the greater output voltage and power. In the same conditions, the energy transformation of the parallel piezoelectric film is more effective than that in series. Discussion and Conclusions The proposed device gathers multi-directional wind into one direction, so that the force centralized on the PVDF thin films and the PVDF film deformation maximize. The results show that the wind speed is almost linear to the output voltage. The sensitivity of the PVDF piezoelectric film is also high.
