Book Description
Energy Harvesting Autonomous Sensor Systems: Design, Analysis, and Practical Implementation provides a wide range of coverage of various energy harvesting techniques to enable the development of a truly self-autonomous and sustainable energy harvesting wireless sensor network (EH-WSN). It supplies a practical overview of the entire EH-WSN system from energy source all the way to energy usage by wireless sensor nodes/network. After an in-depth review of existing energy harvesting research thus far, the book focuses on: Outlines two wind energy harvesting (WEH) approaches, one using a wind turbine generator and one a piezoelectric wind energy harvester Covers thermal energy harvesting (TEH) from ambient heat sources with low temperature differences Presents two types of piezoelectric-based vibration energy harvesting systems to harvest impact or impulse forces from a human pressing a button or switch action Examines hybrid energy harvesting approaches that augment the reliability of the wireless sensor node’s operation Discusses a hybrid wind and solar energy harvesting scheme to simultaneously use both energy sources and therefore extend the lifetime of the wireless sensor node Explores a hybrid of indoor ambient light and TEH scheme that uses only one power management circuit to condition the combined output power harvested from both energy sources Although the author focuses on small-scale energy harvesting, the systems discussed can be upsized to large-scale renewable energy harvesting systems. The book goes beyond theory to explore practical applications that not only solve real-life energy issues but pave the way for future work in this area.

Book Description
Autonomous sensors transmit data and power their electronics without using cables. They can be found in e.g. wireless sensor networks (WSNs) or remote acquisition systems. Although primary batteries provide a simple design for powering autonomous sensors, they present several limitations such as limited capacity and power density, and difficulty in predicting their condition and state of charge. An alternative is to extract energy from the ambient (energy harvesting). However, the reduced dimensions of most autonomous sensors lead to a low level of available power from the energy transducer. Thus, efficient methods and circuits to manage and gather the energy are a must. An integral approach for powering autonomous sensors by considering both primary batteries and energy harvesters is presented. Two rather different forms of energy harvesting are also dealt with: optical (or solar) and radiofrequency (RF). Optical energy provides high energy density, especially outdoors, whereas RF remote powering is possibly the most feasible option for autonomous sensors embedded into the soil or within structures. Throughout different chapters, devices such as primary and secondary batteries, supercapacitors, and energy transducers are extensively reviewed. Then, circuits and methods found in the literature used to efficiently extract and gather the energy are presented. Finally, new proposals based on the authors’ own research are analyzed and tested. Every chapter is written to be rather independent, with each incorporating the relevant literature references. Powering Autonomous Sensors is intended for a wide audience working on or interested in the powering of autonomous sensors. Researchers and engineers can find a broad introduction to basic topics in this interesting and emerging area as well as further insights on the topics of solar and RF harvesting and of circuits and methods to maximize the power extracted from energy transducers.

Book Description
Kinetic energy harvesting converts movement or vibrations into electrical energy, enables battery free operation of wireless sensors and autonomous devices and facilitates their placement in locations where replacing a battery is not feasible or attractive. This book provides an introduction to operating principles and design methods of modern kinetic energy harvesting systems and explains the implications of harvested power on autonomous electronic systems design. It describes power conditioning circuits that maximize available energy and electronic systems design strategies that minimize power consumption and enable operation. The principles discussed in the book will be supported by real case studies such as battery-less monitoring sensors at water waste processing plants, embedded battery-less sensors in automotive electronics and sensor-networks built with ultra-low power wireless nodes suitable for battery-less applications.

Book Description
"Condition monitoring in electrical power networks can reduce maintenance costs, improve supply reliability and provide a real-time measurement of equipment operating conditions. For example, around a transformer we need to control parameters like KV, tap position, temperature of the transformer, oil temperature, buck trip, buck alarm, oil temperature trip, winding temperature alarm, auto tap position control etc. However, wiring monitoring sensors in a substation environment or on a power line and around High Voltage (HV) devices can be very expensive. Using Wireless Sensor Networks (WSNs) would reduce installation costs. Nonetheless, sensors would eventually run out of energy. Another factor to consider is that changing the batteries of sensors located around HV devices can be costly, inconvenient and could potentially involve high personal safety risks. Consequently, for the purpose of condition monitoring, providing an autonomous WSN is of utmost importance. An autonomous WSN eliminates the problem of replacing batteries or recharging them manually. Enabling nodes in the network to harvest energy from their ambient environment may provide us with a self-powering WSN. Fortunately, a substation area is a rich environment for energy harvesting purposes. However, not all the monitoring sensors are necessarily close enough to HV terminals to take advantage of energy harvesting potential.This thesis studies the possibility of deploying an autonomous wireless sensor network in a substation environment. To this end, a hierarchical energy-harvesting model is proposed in which energy is scavenged in two levels. In the first step, energy is scavenged using harvesters that are located close to high voltage terminals. Then a portion of the scavenged energy will be distributed to nearby sensor nodes by radiating radio frequency signals to them. The hierarchical aspect of our model allows us to deal with the non-uniform distribution of the energy harvesting resources.The main goal of this thesis is to evaluate and optimize the performance of the proposed hierarchical energy-harvesting model. To this end, we have studied our system through mathematical analysis and computer simulations. %Our analysis allows us to predict the outage probability for a system, consisting of a number of sensors and with different initial settings. Therefore, the involved parameters can be adjusted to deliver the targeted performance. We also have proposed power allocation techniques to maximize the efficiency of our autonomous WSN.In this work we show that despite the wasteful nature of wireless transfer of energy, a self-sustainable wireless sensor network in a substation area can be accomplished"--

Book Description
The principle of energy harvesting, i. e. gleaning of extremely small amounts of energy from the environment, has been around for a long time. For technical reasons, the idea of operating a wireless link, commercially, with energy from the environment was to date only possible with solar cells, and outdoors where there is sufficient light. EnOcean is the first company to offer commercial solutions for operating wireless links in low-light indoor surroundings, or by energy sources that are an alternate to light. In this paper we will discuss two application scenarios for energy-autonomous sensor/actor networks with partly contrary requirements. The first application scenario is typical for e.g. building automation or environmental monitoring, where the wirelessly operated sensors are distributed over a widespread area and only a few measurement values are generated in a moderate time interval. Modern fabrication facilities with highly flexible manufacturing cells or highly dynamic processes in the military environment, where clusters of sensors and actuators have to be read-out and controlled in a limited space under stringent real-time limitations stand for the second application scenario. We will describe the current status of technology, show measurement results, tell about experiences already made in the field and give a prospective view of possible future developments. Although primarily developed for new application scenarios in building systems engineering, household, logistics, environmental protection and production automation wireless sensor/actor networks based on EnOcean technology can also be tailored to military needs for future air, ground and naval vehicle capabilities.

Book Description
This book discusses in detail the CMOS implementation of energy harvesting. The authors describe an integrated, indoor light energy harvesting system, based on a controller circuit that dynamically and automatically adjusts its operation to meet the actual light circumstances of the environment where the system is placed. The system is intended to power a sensor node, enabling an autonomous wireless sensor network (WSN). Although designed to cope with indoor light levels, the system is also able to work with higher levels, making it an all-round light energy harvesting system. The discussion includes experimental data obtained from an integrated manufactured prototype, which in conjunction with a photovoltaic (PV) cell, serves as a proof of concept of the desired energy harvesting system.

Book Description
Using energy harvesting for powering autonomous sensor systems can meet the goal of perpetual operation. However, the uncertainty in system supply coupled with the size constraints presents challenges in design of such systems. To address these challenges,this thesis is concerned with effective management of harvested-energy for matching supply and demand in order to operate perpetually with uniform performance. The thesis focuses on two fundamental design considerations in addressing these challenges: (i) managing variability of the energy harvesting source, and (ii) matching the demand with energy supply under the influence of non-ideal characteristics of the harvesting system. To address the problem of variability of energy source, the thesis focuses on effective prediction of harvested-energy. An effective approach for evaluating the accuracy of solar energy prediction algorithm is proposed and optimised values of prediction algorithm parameters are determined to minimise prediction error. The problem of achieving uniform performance under the supply variability is addressed by proposing a new prediction based energy management policy. The results of the proposed policy are compared with other recently reported policies and it is shown that the proposed policy achieves up to 41% lower variance in performance and 30% lower dead time of the system, which is important to achieve the goal of perpetual operation. To address the problem of effective matching of supply and demand, the thesis considers the design of photovoltaic energy harvesting supply and storage subsystem in terms of its component's non-ideal characteristics. The influence of these characteristics on supply and demand is identified using modeling of losses and component interdependencies, and empirically validated using a reference system design. Using the proposed modeling, the performance of recently reported energy management policies is evaluated to show that these are ineffective in achieving the goal of perpetual operation, and optimisations are proposed to address this.
