Investigation and characterization of an arc-shaped piezoelectric generator
- 399 Downloads
novel arc-shaped piezoelectric generator based on flexible PVDF thin film is presented and systemically studied. With a periodical external force, the generator can produce peak voltage of 45.6 V and peak power of 30.7 μW. The maximum power density reaches 38.4 μW/cm3 with a 4 cm × 2 cm × 100 μm device, at the optimum load resistance of 33.33 MOhm. The influence of frequency, size dimension and load resistance are investigated through experimental measurements. With this high output arc-shaped generator, capacitors can be effectively charged and three commercial LEDs have been directly lighted without any energy storage unit.
