Electricity-Generating Rug using Piezoelectric Transducers

Abstract

INTRODUCTION

One of the necessities in conforming to the modernized world is electricity. Electricity, on the other hand, has many uses and applications that its supply and demand are observed separately from primary sources. The US Energy Information Administration (EIA, 2018) concluded that in the future, there will be a higher increase in demand for electricity. Renewable energy is a sustainable way to generate power and electricity, and it is very important to develop such various technologies. Electrical energy can be harvested from piezoelectric material (Riyaz, 2016). This research study aimed to construct a device that would generate electricity through application of mechanical pressure.

METHODS

In creating the device, the piezoelectric transducers were soldered together with stranded wires. The red wires were soldered on the inner layer of the transducer, and the black wires were soldered on the outer layer of the transducer. It was then placed between two rugs to create a protective barrier for the transducers to not easily break. The device was tested in persons having three varying weights with different steps.

RESULTS

The device was tested with three persons having different weights (30 kg, 40 kg, and 50 kg). The voltage produced were recorded and tabulated. The average of trial 2 is 7.96 while the average of trial 1 is 7.49, which means that trial 2 is 0.47 more effective in producing electricity than trial 1. Using one-way ANOVA as statistical test, it was concluded that the device produced the highest amount of voltage when the person having the biggest weight applied pressure on it. The statistical test showed that there was a significant difference because the P-values should be less than the significant level. Seeing that was the case, it was then declared that there is significant difference between the data values and the null hypothesis was rejected.

DISCUSSIONS

The Experiment 1 shows that there is a directly proportional relationship between the voltage produced and the mass of the person. This research can help everybody because electricity is part of our daily lives now, living without it would be very difficult. and it would help many households to save on their monthly expenses by just using this because they don't really need to do lots of work to obtain electricity, they just need to walk on it.
