POWER HARVESTING BY USING HUMAN FOOT STEP
In this paper , some of the shortcomings in the existing system has been proposed to be rectified. The advances have allowed numerous ways for power harvesting systems in practical applications in order to meet the power demand. The use of piezoelectric crystal is to generate electric output from surrounding vibrations. Piezoelectric materials have a crystalline structure that they can convert mechanical energy into electrical charge and is vice-versa. These materials have the ability to absorb mechanical energy from their surroundings, usually ambient vibration, and transform it into electrical energy that can be used to power other devices. The produced electrical energy from the piezoelectric crystal is very low in the order of 2-3volts and is initially stored in a 2v rechargeable battery through a charge controller ,since it is not possible to charge a 12V battery through crystal output. In order to increase the voltage, the boost converter circuit is used. The use of boost converter is to increase the level of voltage ranges about 12V and is stored in a 12V battery. In order to supply power to the load an inverter circuit is required by which the generated voltage is fed to the CFL lamp load .This project can be implemented in dense populated areas like railway station ,bus stands etc where more amount of vibration energy will be obtained. In this paper, we discuss about many researches that has been performed in the area of power harvesting. I .INTRODUCTION Man has needed and used energy at an increasing rate for his purpose. Due to this a lot of energy resources have been exhausted and wasted. The utilization of waste energy of foot power with human locomotion is very much relevant for highly populated countries where the roads, railway stations, bus stands, temples, etc. The human bio-energy being wasted if it can be made possible for utilization it will be very useful energy sources. Walking is the most common activity in day to day life. While walking, the person loses energy to the surface in the form of vibration. This energy can be tapped and converted to electrical form. In this paper, piezoelectric crystals were used as a medium. These piezoelectric crystals convert the mechanical vibrations into electrical energy. II. PIEZOELECTRIC CRYSTALS One of the most suitable method for obtaining the energy surrounding a system is achieved by using piezoelectric crystals. Piezoelectric crystals is one of small scale energy sources. The piezoelectric crystals are subjected to vibration they generate a very small voltage, commonly known as piezoelectricity. It has a crystalline structure that converts an applied vibration into an electrical energy .The piezoelectric effect exists in two properties: The first is the direct piezoelectric effect that describes the material " s ability to transform mechanical strain into electrical charge. The second form is the converse effect, which is the ability to convert an applied electrical potential into mechanical strain energy. These properties allows the material to function as a power harvesting medium.

The reducing in energy consumption of portable electronic devices, the concept of gathering renewable energy in human surrounding arouses a renewed interest. This paper focuses on one such a new way of energy harvesting using piezoelectric sensors. Piezoelectric sensors can be used as mechanisms to transfer mechanical energy like vibration, into electrical energy that can be stored and used to power other devices. Piezoelectric sensors have a more application in real life. Some of the new applications are mentioned by the following steps. Nowadays, there is a need to utilize different forms of energy at passenger terminals like railways and airports across the world. Cleaner, more sustainable forms of electrical power are needed in order to keep costs lower, to maintain productive and positive relationships with neighbors and to insure a healthy environment for upcoming future generations. The use of piezoelectric devices are installed in terminals will enable the take of kinetic energy from foot traffic. This energy can be used to offset some of power can be used to operating the lighting systems. These devices are used in a huge number of comforts in our daily lives. With the increase in energy consumption of these portable electronic devices, the concept of gathering alternative renewable energy in human surroundings arise a new interest among us. In this paper we try to develop a new piezoelectric energy generator. That can produce energy from pressure and vibration available on some other term (like people walking). This project describes piezoelectric materials uses in order to produce energy from people walking vibration for generating and accumulating the energy. This concept is also applicable to some large vibration sources which can find from the nature. This system also represents a footstep of piezoelectric energy harvesting model which is cost effective and easy to implement.

International Journal of Electrical and Computer Engineering (IJECE), 2018
Piezoelectric utilization as a generator is an effort to obtain electrical energy that refers to the concept of energy harvesting referring the development of piezoelectric as a generator that converts the pressure or vibration generated from steps into electrical energy that can be used on low-power electronic devices. Because the use of piezoelectric as a generator allows the use in charging low voltage, a larger resource is required in different series. Based on the problem, an energy harvesting device and a voltage amplifier are created to increase the voltage of the pizoelectric output. An arduino microcontroller is used to control the energy harvesting device and voltage booster. It is required approximately 10 steps to charge four AA 1.2 Volt batteries and 80 steps to charge two 12 volt batteries respectively. Keyword: Arduino Conventional energy Microcontroller Piezoelectric Renewable energy source 1. INTRODUCTION The current energy crisis is a problem that greatly affects the survival of human life, especially the problem of electrical energy. The development of technology makes most of human activities are supported by various equipment and technologies that use electrical energy as a source of energy. This certainly makes the electrical energy as an inseparable part in all human activities. The main source of power today is fossil fuel, but fossil fuel is non-renewable natural resource and the availability is limited because it has a certain amount of mass and if used continuously without any restriction it will considerably decrease and run out. The production and use of fossil fuel has a detrimental effect on the environment, and fossil fuels are carbon dioxide producers that produce greenhouse gases. Along with the increasing energy demand and the unbalanced condition between the demand and supply due to the decrease of the fossil fuel supply, the development of alternative energy sources is needed to meet current energy needs. A renewable energy is needed to reduce the use of fossil fuels as a major source of energy for power generation. It is a source of sustainable energy that is available in nature and can be used in a relatively long time so that there is no need to worry about the lack of the resources. Reflecting to the last few years, many studies have been conducted in developing renewable energy sources both in large and small scale. One of the research developments of renewable energy is energy harvest design. Some previous researchers have conducted energy harvesting research such as Kymissis et al. conducting a research on energy harvesting on shoe-use by using micro-generator [1]. When the shoe stepped on, the micro-generator rotates to produce voltage. Energy harvesting in sea and river using small generators is conducted by Taylor et al. [2].

Minor Project Report On " FOOT STEP POWER GENERATION "
In the present era, wireless data transmission techniques are commonly used in electronic devices. For powering them connection needs to be made to the power supply through wires else power may be supplied from batteries. Batteries require charging, replacement and other maintenance efforts. For example, in the applications such as villages, border areas, forests, hilly areas, where generally remote controlled devices are used, continuous charging of the microcells is not possible by conventional charging methods. So, some alternative methods need to be developed to keep the batteries full time charged and to avoid the need of any consumable external energy source to charge the batteries. To resolve such problems, Energy harvesting technique is proposed as the best alternative. There exists variety of energy harvesting techniques but mechanical energy harvesting happens to be the most prominent. This technique utilizes piezoelectric components where deformations produced by different means are directly converted to electrical charge via piezoelectric effect. Subsequently the electrical energy can be regulated or stored for further use. The proposed work in this research recommends Piezoelectricity as an alternate energy source. The motive is to obtain a pollution-free energy source and to utilize and optimize the energy being wasted. In this project, we are going to design a setup that contains few piezoelectric sensors that will be able to generate sufficient amount of voltage by the application of strain on them. In this project, we will use the piezo crystal in the devices which go through vibrations during their functioning. The project will be designed such that its application will be user friendly, flexible and can be used in many applications accordingly. Also, the output current generated will be of sufficient magnitude in order to work efficiently.

Innovation, design and implementation of new technologies leading environment and societal benefits, is the basis of this project, which aims to provide an alternative to an existing product, giving it added value, generating energy cleanly and storing it for reuse. The development of the idea behind the project deals with the need of using piezoelectric transducers to produce energy by harvesting it from the footsteps. Walking is the most common activity in day to day life. When a person walks, he loses energy to the road surface in the form of impact, vibration, sound etc, due to the transfer of his weight on to the road surface, through foot falls on the ground during every step. This energy can be tapped and converted in the usable form such as in electrical form and can be temporarily stored for later use.

In the last few years, there have been many researches in the area of energy harvesting. This increase in research has been brought on by the modern advances in wireless technology and low power electronics such as micro electromechanical systems. The advances have allowed numerous doors to open for energy harvesting systems in practical real world applications. The use of piezoelectric materials to capitalize on the ambient vibrations surrounding a system is one method that has seen a dramatic rise in use for energy harvesting. Piezoelectric materials have a crystalline structure that provides them with the ability to transform mechanical strain energy into electrical charge and, vice versa, to convert an applied electrical potential into mechanical strain. The piezoelectric can be modelled as an AC current source with a resistive load. The model was tested in Pspice. While piezoelectric materials are the major methods of harvesting energy, other methods do exist; for example, one of the conventional methods is the use of induction charging. Inductive charging is an age old technology. The most used inductive charging is the transformers. However, who to transfer large amount of power in between two coils from far away has never been considered until recently. A Multisim model is also tested in comparison with the experimental data. In this paper we discuss the research that has been performed in the area of power harvesting and the future goals that must be achieved for power harvesting systems to find their way into everyday use.
