Abstract
In this era of increasing energy costs and decreasing supplies of fossil fuels, emphasis on protecting the environment and creating sustainable forms of power have become vital, high priority projects for modern society. Thus we developed the Energy Harvesting or the Energy Scavenging systems.
Energy Harvesting systems are used to harvest the normally lost environmental energy and to convert it into electrical energy. An energy scavenging system, instead, is a theoretically endless energy source. In literature many papers describe methodologies to realize the energy-scavenger. A lot of them focus on the conversion of the energy associated to mechanical vibrations since they can be easily found in many environments.
Piezoelectric materials (PZT) can be used as mechanisms to transfer ambient vibrations into electrical energy that can be stored and used to power other devices. Piezoelectric materials form transducers that are able to interchange electrical energy and mechanical motion or force. These materials, therefore, can be used as mechanisms to transfer ambient motion (usually vibration) into electrical energy that may be stored and used to power other devices. By implementing power harvesting devices, we can develop portable systems that do not depend on traditional methods for providing power, such as the battery, which has a limited operating life.
This book focuses on a mass tunable Piezoelectric energy harvester since it is one of the more efficient systems to analyze the mechanical vibrations.
