N2 - A novel bluff body wake energy harvester called Vortex Induced Piezoelectric Energy Converter (VIPEC) was proposed. The VIPEC consists of a circular cylinder, a pivoted beam and several piezoelectric patches. Computational Fluid Dynamic (CFD) simulation coupled fluid, structure and piezoelectric interaction was conducted to research the open circuit voltage and the output power at Reynolds number of 8 × 104. It was revealed that the output power is completed demished when the pivoted beam length is longer than the critical value of 4 times the diameter of the cylinder. The pressure center over the beam has a periodic 'jump' as the shedding vortices slip off the beam. Maximum open circuit voltage was gained approximately 2mV with the beam length be 2 times the diameter of the cylinder, and the output power is 4μW with a load resistance of 1kΩ.
