摘要: In the present study, a rotational piezoelectric (PZT) energy harvester has been designed, fabricated and tested. The design can enhance output power by frequency up-conversion provide desired range from fixed input speed increasing interchangeable planet cover numbers which is novelty of this work. prototype ability to harvest evaluated with four experiments, determine effect speed, numbers, distance between PZTs, PZTs numbers. Increasing shows that it increase power. However, without need or any excitation element. With usage one, two, able 0.414 mW, 0.672 1.566 respectively, at 50 kΩ 1500 rpm, 6.25 Hz bending PZT. Moreover, when three cantilevers are used 35 loads, 6.007 density material 9.59 mW/cm3. It was concluded model could work for may result in longer lifetime
