|標題:||A miniature hydro-energy generator based on pressure fluctuation in Kármán vortex street||Project:||Journal of Intelligent Material Systems and Structures.||摘要:||
A new miniature hydro-energy generator for harnessing energy from Kàrmàn vortex street behind a bluff body in a water flow is developed. The flow energy is converted into electrical energy by an assembly of a cantilevered piezoelectric beam and a flexible diaphragm. An analytical model for the energy harvester is developed. Prototypes of the energy generator are fabricated and tested. Experimental results show that an open-circuit output votage of 120 mVpp and an instantaneous output power of 0.7 nW are generated when the pressure oscillates with an amplitude of nearly 0.3 kPa and a frequency of about 52 Hz.
