This book presents an investigation on integrating wireless sensor nodes including their antennas into fiber metal laminates (FMLs) for the purpose of enabling wireless, material-integrated structural health monitoring. Within the scope of this work, a digital sensor node is presented, which can be fully integrated into a conductive host material. A stainless steel antenna supplies the system with sufficient power to provide the functions required for its intended use. This system enables the wireless readout of sensor data for the detection of damage in FMLs. The application focuses on aerospace components, for the detection of damage in the inner material layers, which are not or only hardly detectable by optical inspection methods. Guided ultrasonic waves in the form of Lamb waves are used for this. The flexible electronics are inserted into the layers of the target material, while the associated antenna is cut into the outer metal layer. This turns the outer metal layer, which would prevent wireless communication from inside the laminate, into an advantage, as the need for an additional, external antenna is eliminated. Two fundamentally different principles can be used as the sensor element. Piezoelectric sensors were already used extensively in structural health monitoring using ultrasound and recently developed piezoresistive sensors, which are designed to be very small, making them highly suitable for material integration. Both types of sensors can be read out with the presented system so that the most appropriate approach can be chosen depending on the application. The suitability of the wireless sensor system for its intended purpose is verified by material-integrated measurements. At the end of this work, it is shown that the raw data of the measurements reproducibly provide a sufficient resolution of the sensor signal to manually identify changes caused by applied reversible, artificial pseudo-defects from reference measurements without any damage. The intended audience of this book are people from the field which are familiar with the basic concepts of electrical engineering or similar regions, embedded system enthusiasts and all readers who like to follow the process of a complete wireless electronic system design from requirements analysis to final material-integrated measurement demonstrations.

Safe and efficient joints are key for improving the structural efficiency of composite aircraft. Therefore, this thesis investigates the potential of multifunctional bondlines, combining structural bonding, disbond arrest features, and structural health monitoring. The central research question is how to achieve a functionally compliant design. This means ensuring disturbances between these functions do not eliminate their benefits regarding the objective of safe and efficient joints. The approach is adding discrete multifunctional disbond arrest features, functionally integrating disbond arrest and sensor functions, to epoxy bondlines. Experimental results indicate some major challenges such as a stiffness conflict for the integrated functions. Nevertheless, securing the epoxy bondline without disturbing its static strength proves successful in the end. In addition, the thesis provides some new insights regarding the functional compliance concept. For example, it strongly suggests considering temporal aspects, such as transient material properties.

***Unmissable, hilarious and kind, this is the first novel from Kathryn Wallace, who blogs as I Know, I Need to Stop Talking*** "SAM! AVA! Get downstairs, NOW. Have you done your TEETH? HAIR? SHOES? Come on, come on, come on, we're going to be bastarding late again. No, I haven't seen Lego Optimus Prime, and nor do I give a shit about his whereabouts. Sam, will you stop winding your sister up and take this model of the Shard that I painstakingly sat up and created for you last night so that I wouldn't be in trouble with your teacher. I mean, so that you wouldn't be in trouble with your teacher. No, it doesn't smell of 'dirty wine'. Well, maybe it does a little bit. Look, Sam, I haven't got time to argue. Just hold your nose and get in the car, okay? AVA! TEETH! HAIR! SHOES!" Gemma is only just holding it together - she's a single parent, she's turning 40 and her seven-year-old daughter has drawn a cruelly accurate picture which locates Gemma's boobs somewhere around her knees. So when her new next-door neighbour, Becky, suggests that Gemma should start dating again, it takes a lot of self-control not to laugh in her face. But Becky is very persuasive and before long Gemma finds herself juggling a full-time job, the increasingly insane demands of the school mums' Facebook group and the tricky etiquette of a new dating world. Not only that, but Gemma has to manage her attraction to her daughter's teacher, Tom, who has swapped his life in the City for teaching thirty six to seven year olds spelling, grammar, basic fractions - and why it's not ok to call your classmate a stinky poo-bum... It's going to be a long year - and one in which Gemma and Becky will learn a really crucial lesson: that in the end, being a good parent is just about being good enough. Readers love this hilarious, fast paced slice of family life: ***** Utterly hysterical - NetGalley Reader ***** Brilliant...

Structural Health Monitoring (SHM) in Aerospace Structures provides readers with the spectacular progress that has taken place over the last twenty years with respect to the area of Structural Health Monitoring (SHM). The widespread adoption of SHM could both significantly improve safety and reduce maintenance and repair expenses that are estimated to be about a quarter of an aircraft fleet's operating costs. The SHM field encompasses transdisciplinary areas, including smart materials, sensors and actuators, damage diagnosis and prognosis, signal and image processing algorithms, wireless intelligent sensing, data fusion, and energy harvesting. This book focuses on how SHM techniques are applied to aircraft structures with particular emphasis on composite materials, and is divided into four main parts. Part One provides an overview of SHM technologies for damage detection, diagnosis, and prognosis in aerospace structures. Part Two moves on to analyze smart materials for SHM in aerospace structures, such as piezoelectric materials, optical fibers, and flexoelectricity. In addition, this also includes two vibration-based energy harvesting techniques for powering wireless sensors based on piezoelectric electromechanical coupling and diamagnetic levitation. Part Three explores innovative SHM technologies for damage diagnosis in aerospace structures. Chapters within this section include sparse array imaging techniques and phase array techniques for damage detection. The final section of the volume details innovative SHM technologies for damage prognosis in aerospace structures. This book serves as a key reference for researchers working within this industry, academic, and government research agencies developing new systems for the SHM of aerospace structures and materials scientists. - Provides key information on the potential of SHM in reducing maintenance and repair costs - Analyzes current SHM technologies and sensing systems, highlighting the innovation in each area - Encompasses chapters on smart materials such as electroactive polymers and optical fibers

Wireless sensor networks have become viable solutions to many commercial and military applications. There is a need to develop standards and robust architectures in this domain which allow effective solutions that can be integrated into existing systems. This research focuses on developing an architecture which supports adaptive, self-healing, and self-aware intelligent wireless sensor networks capable of supporting mobile nodes. Sensor subsystems are crucial in the development of projects such as the Future Combat System, a multi-layered system consisting of soldiers and 18 subsystems connected by a network. The proposed architecture utilizes the SWE, a standard for sensor networks being developed by the OGC, and the I-TRM, a multi-layered technical reference model consisting of a behavior-centric technical reference model, information-centric technical reference model, and control technical reference model. The designed architecture is implemented on MPR2400 motes using the nesC programming language. The architecture supports heterogeneous sensor networks with mobile and immobile sensors nodes.
