Energy Autonomy of Batteryless and Wireless Embedded Systems

Energy Autonomy of Batteryless and Wireless Embedded Systems covers the numerous new applications of embedded systems that are envisioned in the context of aeronautics, such as sensor deployment for flight tests or for structural health monitoring. However, the increasing burden of on-board cabling requires wireless solutions. Moreover, concerns such as safety or system lifetime preclude the use of electrochemical energy storage. Ambient energy capture, storage and management are therefore key topics. This book presents these concepts and illustrates them through actual implementations in airliners.
With five years of experience within this specialist field, the authors present results from actual flight tests via a partnership with Airbus. Basic concepts are summarized, together with practical implementations in airliners, enriching the book through the very specific aspects related to embedded systems deployed in aircraft. This book will appeal to both students and practising engineers in the field.

• Features a complete study of the energy management architecture, from general concepts to specific applications
• Presents results from thorough studies on electrostatic energy storage
• Provides hands-on consideration of industrial implementations in airliners, specifically in harsh environments
• Includes actual results obtained from flight tests
