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

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

Abstract.
Using piezoelectric elements to harvest energy from ambient vibrations has been of great interest over the past few years. Due to the relatively low power output of piezoelectric materials, energy storage devices are used to accumulate harvested energy for intermittent use. Piezoelectric energy harvesting circuits have two schemes: one-stage and two-stage energy harvesting. A one-stage energy harvesting scheme includes a conventional diode bridge rectifier and an energy storage device. In recent years, two-stage energy harvesting ci ....etc

Abstract
Sustainable operation of battery powered wireless embedded systems (such as sensor nodes) is a key challenge, and considerable research effort has been devoted to energy optimization of such systems. Environmental energy harvesting, in particular solar based, has emerged as a viable technique to supplement battery supplies. However, designing an efficient solar harvesting system to realize the potential benefits of energy harvesting requires an in-depth understanding of several factors. For example, solar energy supply is highl ....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

The design, construction and maintenance of buildings has a tremendous impact on our environment and our natural resources. The buildings all together use the one-third of all the energy consumed in the country and two-thirds of all electricity. So the challenges is to build them smart, so that they use a minimum of nonrenewable energy, produce a minimum of pollution and costs a minimum of energy, while increasing the comfort, health and safety of the people who live and work in them. Here comes green buildings which alienates the isolation of ....etc
