Literature Review ' Energy Harvesting from Passive Human Power' Faruk Yildiz Sam Houston State University 'Power Generating Shoe' -used as an alternate source of power Darshan Gowtham 1DS10IM015 Preeti Kumar 1DS10IM034 Syed Zeeshan 1DS10IM053 Yash Chordia 1DS10IM060 Internal Guide: Ms. Reena Y.A Assistant Professor Dept. Of IEM Researchers continue to build high-energy-density batteries, but the amount of energy available in the batteries is not only finite but also low, limiting the lifetime of the system. Extended lifetime of electronic devices is very important and also has more advantages in systems with limited accessibility.

This research studies one form of ambient energy sources: passive human power generated from a shoe/sneaker insole when a person is walking or running and its conversion and storage into usable electrical energy. Based on source characteristics, electrical-energy-harvesting, conversion, and storage circuits were designed, built, and tested for low power electronic applications. ' Design of an electro-mechanical portable system using natural human body movements for electricity generation ' S. Ben Ahmed, B.

Multon Ker Lann Campus, Bruz - France In this article, the authors present the energy potential associated with an electromechanical resonant generator that uses natural movements of the human body during walking motion, as a means of increasing the autonomy of portable electronic systems. The article begins by characterizing the human walk in terms of frequency and hip displacement amplitude. A combined mechanical and electrical study is then conducted in order to determine an order of magnitude for recoverable power.

This paper discusses the use of piezoelectric material to generate electricity. This includes the basic theoretical modelling of the electrical power generation mechanisms and optimization of the piezo-host system. It is shown that with proper configuration, a single piezo-film can generate enough electrical density that can be stored in a rechargeable battery for later usage. One of the promising options is by using piezoelectric material or PZT. PZT can be used as a mechanism to transfer ambient vibrations into electrical energy.

This energy can be stored and used to power up electrical and electronics devices. PZT power generation can provide a conventional alternative to traditional power sources used to operate certain types of sensors/actuators, telemetry, and MEMS devices. Power is a readily available resource with which technology and innovation can be harvested into useful form of energy. There are 6 billion mobile devices across the world; cellphones and other electronic devices are a lifeline for people in developing nations.

Unused power exists in various forms such as industrial machines, human activity, vehicles, structures and environment sources Power Harvesting System in Mobile Phones and Laptops using Piezoelectric Charge Generation Karthik Kalyanaraman, Jaykrishna Babu This paper targets the transformation of mechanical energy to electrical energy using piezoelectric materials. With piezoelectric materials, it is possible to harvest power from vibrating structures. It has been proven that, micro to milliwatts of power can be generated from vibrating materials. In gadgets like mobile phones, television remotes, laptops and other devices which employ key depressions for operation, mechanical vibrations are produced while pressing the keys. If these vibrations are successfully harvested, the resulting energy could serve as an ancillary source of energy for charging the batteries.

Morphology of Design The 7 Phases Concept Generation Solar Solar power is the conversion of sunlight into electricity, either directly using photo voltaic (PV), or indirectly using concentrated solar power (CSP). Solar energy is free, does not cause pollution, can be used in remote areas and is infinite/ forever. It can be harnessed only when daytime and sunny, relatively expensive, unreliable source of energy owing to the needs of climatic conditions. Belkin bulldog plus for mac. The batteries required to harness are large and need storage space. Mechanical Mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.

The law of conservation of mechanical energy states that in an isolated system, the mechanical energy is constant. Piezoelectricity Piezoelectricity is the electric charge that accumulates in certain solid materials in response to applied mechanical stress. It is a feasible source of low energy requirements, reactive to small changes or deflection when applied with suitable load.

It is expensive, the output in form voltage, power and current is less resulting in limited application, fragile upon application of heavy loads. Electromagnetism Electromagnetic energy is a field of energy that exists around magnets and electrical currents. This type of energy is basically the mixture of electric fields and magnetic fields combining together causing the flow of electricity to make things work. It is clean, renewable, non-polluting source of energy which doesn’t have any radioactive components. Feasibility Study Preliminary Design Detailed Design Planning and Production Phase Planning for Distribution Planning for Consumption Planning for Retirement Concept Scoring & Screening Survey Coding Method 1 Method 2 TECHNICAL LIMITATIONS Large mechanical stresses in a piezoelectric material can destroy the alignment of dipoles. Exposure to a strong electric field of opposite polarity will depolarize a piezoelectric material. Piezoelectric ceramics are strong in compression, but weak in tension.

CONCLUSIONS In particular, piezo ceramic materials are especially interesting due to their low cost, flexibility and easy integration into elements such as clothes and shoes. Through the simple configuration and electronics, energy harvesting is possible. In order to get energy values suitable for the functioning of electronic appliances, improvements in the material in order to optimize the energy transfer and precise determination of the geometry and number of the piezoelectric generators should be performed. Circuit The energy generated by the piezo sensor is very less. Hence, it is connected in series with a signal amplifier to amplify the signal. The signal amplifier, is in turn connected to a signal fliter and an impedance buffer which further gives the final signal. The final output can be either connected to a voltmeter to display the reading or a mobile charger to power mobile phones.

Design The piezoelectric sensors are connected in series and parallel in an efficient combination. The combination of sensors are then placed inside the sole of the shoe so that pressure is applied on them during walking.
