Metamaterials have provided applications in spectral ranges covering radio frequencies and ultraviolet. However, most applications have been extrapolated to the visible or near-infrared after being developed at the GHz level. This is due to technological reasons since fabrication of microwave antennas is not as demanding as THz resonators or plasmonic nanostructures. Accordingly, this book has been divided into three parts. In the first part, fundamentals of metamaterials and metadevices are discussed, while describing recent advances in the field. In the second part, the discussion is extended to the different spectral ranges focusing on the strategies for enabling the reconfigurability of metadevices. Given the increasing interest in THz applications, these can be found in the third part.

Scientifically defined in 1880 by the Curie brothers, piezoelectricity - from the Greek piezein, meaning to press (squeeze), and ilektron, meaning amber, a material with electrostatic properties - is a phenomenon with many applications. The related piezoelectric materials have been undergoing a long-lasting evolution over the years until today. The field of organic and inorganic piezoelectric materials is continuously expanding in terms of new substances used, new structures, and new applications. The seven chapters of this book present modern aspects and technological advances in the field of piezoelectric materials and applications. To present a balanced view of the field, some chapters focus on new piezoelectric materials and structures, while others examine interesting applications of piezoelectric sensors, energy harvesters, and actuators.

This book assembles the latest knowledge linked to urban environments and urban socio-eco-technological systems including urban, energy, transport, material, and ecosystems. Urban environments and systems affect every person¿s life in many ways and can have negative impacts on the local and global environment. They create value but sometimes with a high environmental cost from a lifecycle perspective. Therefore, scientists and global leaders call for an urban transition to create more urban environments and systems that are climate-positive, sustainable, and healthy, which is necessary for society to function within the planetary boundaries. This is a great challenge. Huge transformations and new ways of thinking regarding the design and co-existence of technical, social, and ecological systems are necessary to turn the present challenge into opportunities. This book, Urban Transition - Perspectives on Urban Systems and Environments, explores this challenge and several different topics related to possible, probable, or necessary urban transitions in the urban environment. It assembles a variety of authors who present many aspects and the latest knowledge linked to urban transitions of the urban environment and urban socio-eco-technological systems - including urban-, energy-, transport-, building- material- and eco-systems. Furthermore, the importance of urban systems and urban environments is seldom clearly linked to their impact on the environment and humans. This book examines this gap, the crucial issues relating to how urban systems influence the urban structure, and how they can be formed and designed to become more sustainable. It explores the link between the complex systems in cities, the physicality of the built environment, and the living environments for the people. The book proposes a rich garden of ideas to provoke and develop current research, debate, and new forms of practice.

The recent developments in biomedical sensors, wireless communication systems, and information networks are transforming the conventional healthcare systems. The transformed healthcare systems are enabling distributed healthcare services to patients who may not be co-located with the healthcare providers, providing early diagnoses, and reducing the cost in the healthcare section. The developments in medical internet of things (m-IoT) would enable a range of applications, including remote health monitoring through medical-grade wearables to provide homecare for elderlies; virtual doctor-patient interaction to have any time and place access to medical professionals; wireless endoscopic examination; and remotely operated robotic surgery to extend the access to highly skilled surgeons. Wireless body area networks (WBAN) are key enablers of these transformations. These networks connect sensors and actuators to external processing units, which could be placed on the surface of the patient's body or implanted inside the body to connect specific sensors and/or actuators inside, on, and around the body to the data collection points. The success of these networks highly relies on the advent of low-power, low-delay, reliable, and low-cost wireless connectivity solutions. This book covers recent developments in wireless healthcare systems to provide an insight to the technological solutions (e.g. for body area channel propagation models, communication techniques, and energy harvesting/transfer) for wireless body area networks, and emerging applications of medical internet of things and wireless healthcare systems.
