Abstract - In this day and age, it is essential to look for
Even though we didn’t acquire a proper winning position in the competition, we think that a special mention by the judges is really something to motivate us to work on this further.
more ways of generating renewable energy without hampering the environment. However, it is also important to understand the efficiency of such new technologies. One such technology is the concept of piezoelectricity and how it can be used to generate electricity to charge our everyday essential devices like phones and watches.
Thus by experimenting thoroughly, we have come up with the conclusions of the efficiency of such electricity-producing shoes and we have noted the conclusions down in this paper.
This paper deals with one such type of new idea that has been thought of many times previously but has never been implemented properly. That is a shoe that can generate electricity by walking. It uses piezoelectric discs of 27mm diameter which are placed in strategic locations of the shoe for maximum energy output which will be discussed later in this paper.
1.1 The Working of piezoelectricity in relevance to this project: The piezoelectric disc used in this project works on the principle that the quartz or ceramic material it is made up of, produces an electric current upon mechanical stress.
Key Words: Piezoelectricity, Renewable Energy, Efficiency of electricity generation, Electric Shoe
The quartz disc is made up of silicon and oxygen combined with bonds.
1.INTRODUCTION
Oxygen is more electronegative than silicon. Due to this, the bond present between silicon and oxygen is polar.
Piezoelectricity is a principle that talks about electricity generation by applying mechanical stress/force to a piezoelectric crystal in order to generate electricity. It is a simple yet an effective principle to make various innovations useful for the public and governments to generate cost effective energy to power low energy equipment by installing piezoelectric devices.
In its hexagonal structure, the net electric charge is at the centre of the structure. However, due to mechanical stress, it changes position. This change in position leads to the creation of voltage.
The concept of electricity-generating shoes has been thought of many times but has rarely been implemented. However, even in these implementations, the prototypes are often made with such high cost of production that these are not likely to be affordable to the mass middle-class public, especially in regard to India. We have come up with a shoe that requires minimal costs to make the shoe affordable for the larger masses. Even though it might be far from mass production, it is implemented by us and thoroughly tested and experimented, of which the conclusions we have taken to make this research paper.

This shoe was originally made for a competition called Ideation Express conducted by the E-cell of IIT Madras in 2024. Subsequently, we have named the shoe,” PowerKick”.
