Wind Energy Harvesting a Piezocomposite Generating Element
Cam Minh Tri Tien(띠앵민드리),Nam Seo Goo(구남서) 대한기계학회 2010 대한기계학회 춘추학술대회 Vol.2010 No.11
This paper introduces a small scale windmill which uses the PCGE for harvesting wind energy. Current technology uses large windmills that operate in rural regions and have complex generating mechanisms such as towers, blades gears, speed controls, magnets, and coils. In city, wind energy that would otherwise be wasted can be reclaimed and stored for later use. In this study, we therefore introduce a small scale windmill that can work in urban areas. In the prototype, a PCGE performs as a secondary beam. The results show that the device can successfully harvest the wind energy.

Energy can be reclaimed and stored for later use to recharge a battery or power a device through a process called energy harvesting. Piezoelectric is being widely investigated for use in harvesting energy from motion such as body movement and machine vibration. This paper presents a simple analytical model to describe output voltage effectiveness of a Piezo-Composite Generating Element (PCGE) from vibration and its experimental verification. PCGE is composed of layers of carbon/epoxy, PZT ceramic and glass/epoxy. During the manufacturing process, the stacked layers were cured at an elevated temperature of 177℃ in an autoclave, which made the PCGE pre-stressed due to a mismatch in the coefficients of thermal expansion between the constituent layers. For the experiments, three kinds of lay-up configurations of PCGE were utilized to verify the model and to approve its ability to convert oscillatory mechanical energy into electrical energy. The predicted performances are much in agreement with experimental ones.
