Explanations of fundamental physical properties such as piezoelectricity and pyroelectricity are included to aid the understanding of the non-specialist. Specific technologies and particular applications are also presented. This book is divided into two parts, each subdivided into chapters. Part I concerns fundamentals. Chapter 1 reports the discoveries, standard issues and various materials involved with energy harvesting. Chapter 2 presents electromechanical models enabling an understanding of how energy harvesting systems behave. The vibration theory and designs for various piezoelectric energy harvesting structures are addressed in Chapter 3.

A description of the conversion enhancement for powering low-energy consumption devices is presented in Chapter 5. Part II concerns Applications and Case Studies. It begins with Chapter 6, in which the principles and applications of piezoelectric nanogenerators are reported. Chapter 7 describes the utilization of energy harvesting from low-frequency energy sources. There are more ways to use vibrational energy than waste heat. However, Chapter 8 presents the fundamentals of an important application of heat conversion with a copolymer. Finally, commercial energy harvesting products and a technological forecast are provided in Chapter 9.

Book Description
Environmental pollution has been one of the main challenges for sustainable development. Piezoelectric materials can be used as a means of transforming ambient vibrations into electrical energy to power devices. The focus is on an alternative approach to scavenge energy from the environment. This book presents harvesting methodologies to evaluate the potential effectiveness of different techniques and provides an overview of the methods and challenges of harvesting energy using piezoelectric materials. Piezoelectric energy harvesters have many applications, including sensor nodes, wireless communication, microelectromechanical systems, handheld devices, and mobile devices. The book also presents a new approach within piezoelectric energy harvesting using the impact of raindrops. The energy-harvesting model presented is further analyzed for single-unit harvester and an array of multiple harvesters to maximize the efficiency of the device.

Book Description
The goal of this dissertation consists of improving the efficiency of energy harvesting using pyroelectric and piezoelectric materials in a system by the proper characterization of electrical parameters, widening frequency, and coupling of both effects with the appropriate parameters. A new simple stand-alone method of characterizing the impedance of a pyroelectric cell has been demonstrated. This method utilizes a Pyroelectric single pole low pass filter technique, PSLPF. Utilizing the properties of a PSLPF, where a known input voltage is applied and capacitance Cp and resistance Rp can be calculated at a frequency of 1 mHz to 1 Hz. This method demonstrates that for pyroelectric materials the impedance depends on two major factors: average working temperature, and the heating rate. Design and implementation of a hybrid approach using multiple piezoelectric cantilevers is presented. This is done to achieve mechanical and electrical tuning, along with bandwidth widening. In addition, a hybrid tuning technique with an improved adjusting capacitor method was applied. An toroid inductor of 700 mH is shunted in to the load resistance and shunt capacitance. Results show an extended frequency range up to 12 resonance frequencies (300% improvement) with improved power up to 197%. Finally, a hybrid piezoelectric and pyroelectric system is designed and tested. Using a voltage doubler, circuit for rectifying and collecting pyroelectric and piezoelectric voltages individually is proposed. The investigation showed that the hybrid energy is possible using the voltage doubler circuit from two independent sources for pyroelectrictity and piezoelectricity due to marked differences of optimal performance.

Book Description
In the U.S., there are over 4 million miles (6 million km) of roadways and more than 250 million registered vehicles. The energy lost in the pavement system due to traffic-induced vibration and deformation is enormous. If effectively harvested, such waste energy can serve as an alternative sustainable energy source that can be easily integrated to the transportation system. To harness this forms of energy, the common approach is to utilize a piezoelectric module, which generates electricity when strained. In this thesis, literature review based on different energy harvesting methods has been made.The potential of PVDF, which is a piezoelectric as well as pyroelectric polymer material, is investigated as a potential piezoelectric energy harvester integrated in pavement systems. However, the potential of PVDF as a hybrid piezo-pyroelectric energy harvester has been seldom studied. Through series of well controlled experiments, it is found that there exists interesting coupling phenomenon between piezoelectric and pyroelectric effects of PVDF: the voltage generated by simultaneous mechanical and thermal stimulations is the sum of voltages generated by separate stimulations. In addition, an estimation of power generation through piezoelectric and pyroelectric effect is conducted. The overall effects of temperature on hybrid piezo-pyroelectric energy harvesting piezo and pyro constant varies with temperature are discussed in the end.

Book Description
This book covers the topic of vibration energy harvesting using piezoelectric materials. Piezoelectric materials are analyzed in the context of their electromechanical coupling, heterogeneity, microgeometry and interrelations between electromechanical properties. Piezoelectric ceramics and composites based on ferroelectrics are advanced materials that are suitable for harvesting mechanical energy from vibrations using inertial energy harvesting which relies on the resistance of a mass to acceleration and kinematic energy harvesting which couples the energy harvester to the relative movement of different parts of a source. In addition to piezoelectric materials, research efforts to develop optimization methods for complex piezoelectric energy harvesters are also reviewed. The book is important for specialists in the field of modern advanced materials and will stimulate new effective piezotechnical applications.
