Harvesting energy from planetary gear using piezoelectric material
: 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 and provide the desired output power range from a fixed input rotational speed by increasing the interchangeable plane...

description |
: 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 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 PZTs numbers. 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. |
