WIRELESS BATTERY CHARGING SYSTEM USING RADIO FREQUENCY ENERGY HARVESTING



INTRODUCTION AND MOTIVATION

Cellular telephone technology became commercially available in the 1980 s. Since then, it has been like a snowball rolling downhill, ever increasing in the number of users and the speed at which the technology advances. When the cellular phone was first implemented, it was enormous in size by today s standards. This reason is two-fold; the battery had to be large, and the circu ....etc

Abstract

It seems these days that everyone has a cellular phone. Whether yours is for business purposes or personal use, you need an efficient way of charging the battery in the phone. But, like most people, you probably don t like being tethered to the wall. Imagine a system where your cellular phone battery is always charged. No more worrying about forgetting to charge the battery. Sound Impossible?
It is the focus of this thesis to discuss the first step toward re ....etc

adaptive piezoelectric energy harvesting circuit ppt

Abstract

This paper describes an approach to harvesting electrical energy from a mechanically excited piezoelectric element. A vibrating piezoelectric device differs from a typical electrical power source in that it has a capacitive rather than inductive source impedance, and may be driven by mechanical vibrations of varying amplitude. An analytical expression for the optimal power flow from a rectified piezoelectric device is derived, and an energy harvesting circuit is proposed which ca ....etc

Energy Harvesting Using Piezoelectric Crystal

ABSTRACT
Energy Harvesting Using Piezoelectric Crystal
Abstract:
This project aims at the harvesting electrical energy from the piezoelectric crystals by the exertion of pressure on them . It is a process of converting the mechanical energy (i.e. vibration) into electrical energy (i.e. voltage) and then using this energy to store in capacitor and use by proper signal conditioning circuit. Piezoelectric materials have the unique ability to interchange electrical and mechanical energ ....etc

A new technology that provides a promising solution for the design of self-powered micro systems. The collection of energy from the Micro-Electro Mechanical System (MEMS) is an emerging alternative to collect energy from natural sources. It has ample potential in wireless sensor applications to provide a natural energy source that is essentially inexhaustible. It is an increasingly attractive alternative to expensive batteries. This essentially free energy source is available without maintenance for the lifetime of the application. Many systems ....etc

GREEN ENERGY HARVESTING TECHNOLOGY IN 3D IC


: INTRODUCTION

An environmentally sustainable IT hardware opens the era of GREEN ELECTRONICS. The practice of designing, use and disposal of peripherals should be done with minimal or no effects on the environment. The three dimensional integrated circuit (3D IC) is the most promising technology route for bridging the huge gap of energy demand and supply of today and tomorrow. This technology focuses on a memory on logic 3D IC in whi ....etc
