Electromagnetic Vibration Energy Harvesting Devices
Electromagnetic vibration transducers are seen as an effective way of harvesting ambient energy for the supply of sensor monitoring systems. Different electromagnetic coupling architectures have been employed but no comprehensive comparison with respect to their output performance has been carried out up to now. Electromagnetic Vibration Energy Harvesting Devices introduces an optimization approach which is applied to determine optimal dimensions of the components (magnet, coil and back iron). Eight different commonly applied coupling architectures are investigated. The results show that correct dimensions are of great significance for maximizing the efficiency of the energy conversion. A comparison yields the architectures with the best output performance capability which should be preferably employed in applications. A prototype development is used to demonstrate how the optimization calculations can be integrated into the design–flow. Electromagnetic Vibration Energy Harvesting Devices targets the designer of electromagnetic vibration transducers who wishes to have a greater in-depth understanding for maximizing the output performance.
Chips 2020
The chips in present-day cell phones already contain billions of sub-100-nanometer transistors. By 2020, however, we will see systems-on-chips with trillions of 10-nanometer transistors. But this will be the end of the miniaturization, because yet smaller transistors, containing just a few control atoms, are subject to statistical fluctuations and thus no longer useful. We also need to worry about a potential energy crisis, because in less than five years from now, with current chip technology, the internet alone would consume the total global electrical power! This book presents a new, sustainable roadmap towards ultra-low-energy (femto-Joule), high-performance electronics. The focus is on ...
Handbook of Energy Harvesting Power Supplies and Applications
This book describes the fundamentals and principles of energy harvesting and provides the necessary theory and background to develop energy harvesting power supplies. It explains the overall system design and gives quantitative assumptions on environmental energy. It explains different system blocks for an energy harvesting power supply and the trade-offs. The text covers in detail different energy transducer technologies such as piezoelectric, electrodynamic, and thermoelectric generators and solar cells from the material to the component level and explains the appropriate power management circuits required in these systems. Furthermore, it describes and compares storage elements such as secondary batteries and supercapacitors to select the most appropriate one for the application. Besides power supplies that use ambient energy, the book presents systems that use electromagnetic fields in the radio frequency range. Finally, it discusses different application fields and presents examples of self-powered electronic systems to illustrate the content of the preceding chapters.
CMOS Circuits for Electromagnetic Vibration Transducers
Chip-integrated power management solutions are a must for ultra-low power systems. This enables not only the optimization of innovative sensor applications. It is also essential for integration and miniaturization of energy harvesting supply strategies of portable and autonomous monitoring systems. The book particularly addresses interfaces for energy harvesting, which are the key element to connect micro transducers to energy storage elements. Main features of the book are: - A comprehensive technology and application review, basics on transducer mechanics, fundamental circuit and control design, prototyping and testing, up to sensor system supply and applications. - Novel interfacing conce...

Material-Integrated Intelligent Systems
Combining different perspectives from materials science, engineering, and computer science, this reference provides a unified view of the various aspects necessary for the successful realization of intelligent systems. The editors and authors are from academia and research institutions with close ties to industry, and are thus able to offer first-hand information here. They adopt a unique, three-tiered approach such that readers can gain basic, intermediate, and advanced topical knowledge. The technology section of the book is divided into chapters covering the basics of sensor integration in materials, the challenges associated with this approach, data processing, evaluation, and validation, as well as methods for achieving an autonomous energy supply. The applications part then goes on to showcase typical scenarios where material-integrated intelligent systems are already in use, such as for structural health monitoring and smart textiles.
Der bankbetriebliche Zahlungsverkehr
Seit Beginn der 3. Stufe der Europäischen Wirtschafts- und Währungsunion müssen europäische Banken mit internationaler Ausrichtung an einer Vielzahl unterschiedlicher Zahlungsverkehrssysteme und Abwicklungsverfahren teilnehmen. Diese Eingebundenheit in heterogene Zahlungsverkehrsinfrastrukturen erfordert bankseitig vielfältige abwicklungstechnische Anpassungen; zugleich zwingen die Marktbedingungen zu einer Umgestaltung der Geschäftsmodelle im Zahlungsverkehr. Das Buch analysiert den sich abzeichnenden Paradigmenwechsel in der bankbetrieblichen Zahlungsverkehrsabwicklung: Der Autor nimmt auf Basis eines ökonomischen Analyserahmens eine Bewertung aktueller Zahlungsverkehrssysteme vor und untersucht drängende infrastrukturseitige und geschäftspolitische Herausforderungen. Daran anknüpfend werden Lösungsansätze im Bereich des Zahlungsverkehrs-Outsourcings, der Prozessgestaltung sowie des Innertagesliquiditätsmanagements entwickelt.

Die sieben Todsünden
Sieben Todsünden Neun Illustratoren Vierzehn Autoren Ein guter Zweck „Todsünde“ – ein gewaltiger Begriff, den man zwar umgangssprachlich verwendet, der jedoch theologisch gesehen völlig falsch ist. Was wir darunter verstehen, bezeichnet die sieben Hauptlaster – schlechte Charaktereigenschaften, die uns posthum ein warmes Plätzchen im Höllenfeuer reservieren. Dass aus Todsünden jedoch auch Gutes entstehen kann, beweist diese Anthologie voller spannender, lustiger, guter und böser Geschichten, Gedichte und Illustrationen. Wir Autoren und Illustratoren haben auf ein Honorar verzichtet – zugunsten einer Familie, die im christlichen Glauben Halt findet. Einer der vier Söhne leidet an Muskeldystrophie. Den Todsünden setzen wir eines vehement entgegen: Nächstenliebe
