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