摘要

. 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.
