Application of computing and communication systems towards monitoring physical devices enables the Industrial Internet, a smart system of sensors integrated within physical objects. A major challenge associated with designing a practical system of sensors is designing an economically viable means to power them at such a large scale, which a wireless power transmission system could facilitate. This thesis addresses the challenge of selecting an appropriate strategy for power transmission and demonstrating its feasibility within a household environment. The first part of the thesis examines potentially feasible strategies for transmitting power to sensors in a household setting. Existing technologies are surveyed and evaluated against the functional requirements associated with this application. Resonant inductive coupling is selected based on its suitability towards the desired application for reasons of power level, safety, obtrusiveness, and efficiency. The second part of the thesis describes the processes of design, simulation, fabrication, and testing of a prototype resonant inductively coupled power transmission system. An accelerometer-based sensor module that communicates via radio frequency is powered by a resonant inductively coupled power transmission system, which consists of a large (1.07 m diameter) transmitter coil embedded within a table and a small (0.038 m diameter) receiver coil adhered to a water bottle. A suitable amount of power is supplied to the receiver module when it is placed within 95% of the primary coil diameter up to a height of 20 cm, and up to a vertical height of about 40 cm along the central axis of the primary coil.

Wireless sensors and sensor networks (WSNs) are nowadays becoming increasingly important due to their decisive advantages. Different trends towards the Internet of Things (IoT), Industry 4.0 and 5G Networks address massive sensing and admit to have wireless sensors delivering measurement data directly to the Web in a reliable and easy manner. These sensors can only be supported, if sufficient energy efficiency and flexible solutions are developed for energy-aware wireless sensor nodes. In the last years, different possibilities for energy harvesting have been investigated showing a high level of maturity. This book gives therefore an overview on fundamentals and techniques for energy harvesting and energy transfer from different points of view. Different techniques and methods for energy transfer, management and energy saving on network level are reported together with selected interesting applications. The book is interesting for researchers, developers and students in the field of sensors, wireless sensors, WSNs, IoT and manifold application fields using related technologies.

This book addresses the design challenges in near-field wireless power transfer (WPT) systems, such as high efficiency, compact size, and long transmission range. It presents new low-profile designs for the TX/RX structures using different shapes of defected ground structures (DGS) like (H, semi-H, and spiral-strips DGS). Most near-field WPT systems depend on magnetic resonant coupling (MRC) using 3-D wire loops or helical antennas, which are often bulky. This, in turn, poses technical difficulties in their application in small electronic devices and biomedical implants. To obtain compact structures, printed spiral coils (PSCs) have recently emerged as a candidate for low-profile WPT systems. However, most of the MRC WPT systems that use PSCs have limitations in the maximum achievable efficiency due to the feeding method. Inductive feeding constrains the geometric dimensions of the main transmitting (TX)/receiving (RX) resonators, which do not achieve the maximum achievable unloaded quality factor. This book will be of interest to researchers and professionals working on WPT-related problems.

Engineering solutions to the development of techniques to transfer power without any physical medium have been envisioned for quite some time to mitigate the complexity involved in the wiring of electronic and electrical systems. Various attempts to demonstrate power-beaming phenomena have met with some success, as industry keeps searching for new approaches and methods. Our work has been involved with the specific application of a wireless power transmission system to be used on the heat shield of a spacecraft. A proof-of-concept design to power multiple sensor modules energized by a central transmitter station has been designed and tested. During the course of the project, interesting observations have been noted and documented. With limited available research on the topic, we have proposed and formulated theoretical analyses and conclusions based on observational data derived from the tests performed on the modules built. This work contributes to this new, little explored area of research, and suggests future uses of the system for other applications.

Wireless power transfer allows the transfer of energy from a transmitter to a receiver across an air gap, without any electrical connections. Technically, any device that needs power can become an application for wireless power transmission. The current list of applications is therefore very diverse, from low-power portable electronics and household devices to high-power industrial automation and electric vehicles. With the rise of IoT sensor networks and Industry 4.0, the presence of wireless energy transfer will only increase. In order to improve the current state of the art, models are being developed and tested experimentally. Such models allow simulating, quantifying, predicting, or visualizing certain aspects of the power transfer from transmitter(s) to receiver(s). Moreover, they often result in a better understanding of the fundamentals of the wireless link. This book presents a wonderful collection of peer-reviewed papers that focus on the modelling of wireless power transmission. It covers both inductive and capacitive wireless coupling and includes work on multiple transmitters and/or receivers.

Wireless power transmission technology offers a wide range of industrial and biomedical applications and could lead to clean sources of electricity for a variety of users. In this technique, conventional power sources are replaced with power transmission devices, such as coils, and electric power storage devices, such as capacitors. Electronic devices, equipped with wireless power transmission systems, can operate for longer periods without the malfunctions caused by their low battery capacity. One of the main objectives in wireless power transfer is to obtain high efficiency in the system. Several parameters can affect the efficiency, such as the coil's structure, distance between coils, load on the receiver side, number of simultaneous loads connected to one transmitter, and electric properties of WPT environment. Some of these parameters can be determined initially and properly be treated; other parameters such as load, distance between coils and environment change are more chaotic and require real-time and in situ treatment. The main purpose of this dissertation is to address the power efficiency enhancement techniques, such as real-time matching configuration and methods to increase the efficiency of the transmitted power. This thesis presents a novel-matching approach and dynamic impedance matching using capacitor matrix for real-time impedance matching. Additionally, a unique approach is presented for transmitting the RF power through an arbitrary medium and using open ended coils to locally perform the power distribution to the load nodes. A comprehensive study on the WPT subsystems has presented in FEM and circuit model simulations.
