Hardback. Etat : New. A fibre Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fibre that reflects particular wavelengths of light and transmits all the others. As such, FBGs can be used as inline optical filters to block certain wavelengths, or as wavelength-specific reflectors. Applications include optical fibre communications, sensors and fibre lasers. This book addresses the critical challenge of developing Fibre Bragg Gratings (FBGs) for applications as sensors in harsh and space environment. Coverage ranges from the basic principles through design, fabrication, and testing to their industrial implementation. A thorough review includes the in-depth examination of the FBGs properties and the most important developments in devices and applications. A particular emphasis is given to the applications of fibre optic sensors in the space environment, which is characterized mainly by vacuum, high thermal gradients, mechanical vibrations and various types of cosmic radiation. The book concludes with a summary and overview of challenges faced by FBG technology. The book is supplemented by an extensive survey of published papers, books and conference reports. As an added benefit, the book is structured in such a way as to provide useful and in-depth training and skills development to graduate/undergraduate students, specialised engineers, and academic/industrial experts.…

Hardback. Etat : New. Self-healing materials are an emerging class of smart materials that are capable of repairing themselves from damage, either spontaneously or under a stimulus such as light, heat, or the application of a solvent. Intended for an audience of researchers in academia and industry, this book addresses a wide range of self-healing materials and processes, with emphasis on their performance in the space environment. This revised, expanded and updated second edition addresses the key concepts of self-healing processes, from their occurrences in nature through to recent advances in academic and industrial research. It includes a detailed description and explanation of a wide range of materials and applications such as polymeric, anticorrosion, smart paints, and carbon nanotubes. Emphasis is given to performance in the space environment, addressing vacuum, thermal gradients, mechanical vibrations, and space radiation. Innovations in controlling self-healing materials for space debris mitigation are also covered. The book concludes with a comprehensive outlook into the future developments and applications of self-healing materials. …

Hardback. Etat : New. As wearable microelectronics are becoming ubiquitous, there is a growing interest in replacing batteries with a means of harnessing power from the user's environment via embedded systems. Efforts have been made to prolong the harvester's operational lifetime, overcoming energy dissipation, lowering resonant frequency, attaining multi-resonant states, and widening the operating frequency bandwidth of the biomechanical energy harvesters. Such technological advances mean harvesting energy is a viable solution for sustainably powering wearable electronics for health and wellbeing applications, such as continuous medical health monitoring, remote sensing, and motion tracking. The book introduces the concepts of vibration-based piezoelectric, electromagnetic and hybrid energy harvesters, and addresses their modelling, fabrication and characterization. It covers the fundamental principles and details the most advanced functions, including biomechanical and space applications. Detailed descriptions and explanations of a wide range of related concepts are provided, such as multi-degrees of freedom hybrid piezo-electromagnetic insole energy harvesters, non-linear 3D printed electromagnetic vibration energy harvesters, and finite element analysis of hybrid piezoelectric and electromagnetic energy harvesting. Also included are trends towards design, modelling, fabrication, and characterization of nonlinear multimodal electromagnetic and hybrid piezo-electromagnetic insole energy harvesters, as well as describing and explaining electromagnetic and hybrid piezo-electromagnetic energy harvesting technologies. The book provides an extensive and up-dated survey of the published scientific and technical articles and conference reports, covering more than 340 references. The book concludes with an outlook from the authors on likely future developments and applications. Energy Harvesting for Wireless Sensing and Flexible Electronics through Hybrid Technologies provides in-depth coverage of the topic for researchers from academia and industry, as well as advanced students with an interest in the field.…
