This seminar 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 can achieve this optimal power flow.

Abstract

The DELTA Smart House is going to have a large number of sensors and microelectronic devices located throughout the house. These devices will need a clean, reliable source of energy that wonâ„¢t need constant maintenance. The goal of this seminar is to discuss utilization of piezoelectric energy sources to provide power to certain applications in the house. Initially an energy scavenging floor that used piezoelectric transducers to harvest wasted energy in the foot strike of a human being. In consideration of the high cos ....etc

Abstract
This seminar investigates and compares the efficiencies of four different interfaces for vibration-based energy harvesting systems. Among those four circuits, two circuits adopt the synchronous switching technique, in which the circuit is switched synchronously with the vibration. In this study, a simple source-less trigger circuit used to control the synchronized switch is proposed and two interface circuits of energy harvesting systems are designed based on the trigger circuit. To validate the effectiveness of the proposed circuit ....etc

ABSTRACT

The objective of this project is to design electronic energy meter. Presently With the help of electromagnetic energy meter the amount of the electricity usage can be calculated. This project helps to design electronic energy meter. To identify the amount of the power used by the house can be calculated using I sense and V sense. V sense contains the Potential transformer rectifier unit and the Zener diode. Zener diode is used for the function of maintain the voltage level up to 5V. I sense contains the current transformer re ....etc

Residential Piezoelectric Energy Sources




Technical Overview
Piezoelectric materials exhibit the unique property known as the piezoelectric effect. When these materials are subjected to a compressive or tensile stress, an electric field is generated across the material, creating a voltage gradient and a subsequent current flow. This effect stems from the asymmetric nature of their unit cell when a stress is applied. As seen in Figure 1, the unit cell contains a s ....etc
