ABSTRACT

          Piezoelectricity has been present in our everyday

lives, however harnessing its full potential in producing

renewable electricity has not been thoroughly

explored. In this study, piezoelectric nanogenerators

in a form of piezoelectric transducers were tested

on its ability to produce electricity using an outside

source of kinetic energy from falling water. The

researchers ran an experiment using a pressure

washer with 1600 psi of water pressure and 1.8

gallons per minute on a device with 14 pieces of

piezoelectric transducers. It was found that the

device produced a consistent 4V and 0.01mAh

(direct current), and was more frequent in longer

duration. Therefore, the researchers concluded

that under a constant water pressure and volume,

the device performs consistently in electricity

production, and time is a big factor in its

performance. In addition, piezoelectric nanogenerators have a high voltage production but are low in ampere.
