In this work, lumped element modeling techniques are used to model the behavior of the piezoelectric transducer. Two system-level models are presented, one using a full lumped element model (LEM) of the transducer and the other using a simplified resonant transducer model. The finite losses in the PRC are included in both models. An experimental test bed is developed, which includes several piezoelectric transducers and a discrete PRC implementation. Through experimental characterization of the energy harvesting system, it is shown that the full LEM accurately captures the behavior of the system over a range of vibration frequencies, while the simplified resonant model is only valid at a single operating frequency. The effects of modeling losses in the power converter are also demonstrated. For the specific systems implemented in this work, is it shown that an ideal model with zero losses overpredicts the power delivered to the load by 30-50%.

This book covers a range of devices that use piezoelectricity to convert mechanical deformation into electrical energy and relates their output capabilities to a range of potential applications. Starting with a description of the fundamental principles and properties of piezo- and ferroelectric materials, where applications of bulk materials are well established, the book shows how nanostructures of these materials are being developed for energy harvesting applications. The authors show how a nanostructured device can be produced, and put in context some of the approaches that are being investigated for the development of nanostructured piezoelectric energy harvesting devices, also known as nanogenerators. There is growing interest in strategies for energy harvesting that use a variety of existing and well-known materials in new morphologies or architectures. A key change of morphology to enable new functionality is the nanostructuring of a material. One area of particular interest is self-powered devices based on portable energy harvesting. The charging of personal electronic equipment and other small-scale electronic devices such as sensors is a highly demanding environment that requires innovative solutions. The output of these so-called nanogenerators is explained in terms of the requirements for self-powered applications. The authors summarise the range of production methods used for nanostructured devices, which require much lower energy inputs than those used for bulk systems, making them more environmentally friendly and also compatible with a wide range of substrate materials.

Ambient energy harvesting has attracted significant attention over the last years for applications such as wireless sensors, implantable devices, health monitoring systems, and wearable devices. The methods of vibration-to-electric energy conversion can be included in the following categories: electromagnetic, electrostatic, and piezoelectric. Among various techniques of vibration-based energy harvesting, piezoelectric transduction method has received the most attention due to the large power density of the piezoelectric material and its simple architectures. In contrast to electromagnetic energy harvesting, the output voltage of a piezoelectric energy harvester is high, which can charge a storage component such as a battery. Compared to electrostatic energy harvester, the piezoelectric energy harvester does not require an external voltage supply. Also, piezoelectric harvesters can be manufactured in micro-scale, where they show better performance compared to other energy harvesters, owing to the well-established thick-film and thin-film fabrication techniques. The main drawback of the linear piezoelectric harvesters is that they only retrieve energy efficiently when they are excited at their resonance frequencies, which are usually high, while they are less efficient when the excitation frequency is distributed over a broad spectrum or is dominant at low frequencies. High-frequency vibrations can be found in machinery and vehicles could be used as the energy source but, most of the vibration energy harvesters are targeting at low-frequency vibration sources which are more achievable in the natural environment. One way to overcome this limitation is by using the frequency-up-conversion technology via impacts, where the source of the impacts can be one or two stoppers or more massive beams. The impact makes the piezoelectric beam oscillate in its resonance frequency and brings nonlinear behavior into the system. The goal of this research is to enhance the piezoelectric harvester's energy retrieving performance from ambient vibrations with low or varying frequencies. In this work, impact-based piezoelectric energy harvesters were studied by discontinuous mapping dynamics. Discontinuous dynamics has been extensively applied in mechanical dynamics and physics field. Since the nature of the most environmental vibrations is periodic, periodic motions of the impact-based piezoelectric harvester were studied. Four different possible motion phases have been identified and categorized based on the performance of the output energy of the system. Many periodic motions are possible depending on the physical properties of the energy harvester setup. So far, we studied three different periodic motions of two beams interacting with each others, where period-1 and period-2 motions of the system are predicted. The stability of the system were analyzed and bifurcation graphs for each periodic motions were presented.

Energy harvesting technology has the ability to create autonomous, self-powered electronic systems that do not rely on battery power for their operation. The term energy harvesting describes the process of converting ambient energy surrounding a system into useful electrical energy through the use of a specific material or transducer. A widely studied form of energy harvesting involves the conversion of mechanical vibration energy into electrical energy using piezoelectric materials, which exhibit electromechanical coupling between the electrical and mechanical domains. Typical piezoelectric energy harvesting systems are designed as add-on systems to a host structure located in a vibration rich environment. The added mass and volume of conventional vibration energy harvesting designs can hinder to the operation of the host system. The work presented in this dissertation focuses on advancing piezoelectric energy harvesting concepts through the introduction of multifunctionality in order to alleviate some of the challenges associated with conventional piezoelectric harvesting designs. The concept of multifunctional piezoelectric self-charging structures is explored throughout this work. The operational principle behind the concept is first described in which piezoelectric layers are directly bonded to thin-film battery layers resulting in a single device capable of simultaneously harvesting and storing electrical energy when excited mechanically. Additionally, it is proposed that self-charging structures be embedded into host structures such that they support structural load during operation. An electromechanical assumed modes model used to predict the coupled electrical and mechanical response of a cantilever self-charging structure subjected to harmonic base excitation is described. Experimental evaluation of a prototype self-charging structure is then performed in order to validate the electromechanical model and to confirm the ability of the device to operate in a self-charging manner. Detailed strength testing is also performed on the prototype device in order to assess its strength properties. Static three-point bend testing as well as dynamic harmonic base excitation testing is performed such that the static bending strength and dynamic strength under vibration excitation is assessed. Three-point bend testing is also performed on a variety of common piezoelectric materials and results of the testing provide a basis for the design of self-charging structures for various applications. Multifunctional vibration energy harvesting in unmanned aerial vehicles (UAVs) is also investigated as a case study in this dissertation. A flight endurance model recently developed in the literature is applied to model the effects of adding piezoelectric energy harvesting to an electric UAV. A remote control foam glider aircraft is chosen as the test platform for this work and the formulation is used to predict the effects of integrating self-charging structures into the wing spar of the aircraft. An electromechanical model based on the assumed modes method is then developed to predict the electrical and mechanical behavior of a UAV wing spar with embedded piezoelectric and thin-film battery layers. Experimental testing is performed on a representative aluminum wing spar with embedded self-charging structures in order to validate the electromechanical model. Finally, fabrication of a realistic fiberglass wing spar with integrated piezoelectric and thin-film battery layers is described. Experimental testing is performed in the laboratory to evaluate the energy harvesting ability of the spar and to confirm its self-charging operation. Flight testing is also performed where the fiberglass spar is used in the remote control aircraft test platform and the energy harvesting performance of the device is measured during flight.
