    Lucas Anthony Ciccarelli, M.Sc. received a bachelor's degree in mechanical engineering from Philadelphia University in 2013 and received his master's degree in textile engineering from RWTH Aachen University in 2017. Both degrees consisted of focus and research in fiber-reinforced composite materials. He now holds a position as a project and sales engineer for thermoplastic-composites production equipment at AFPT GmbH in Dörth, Germany.
    Prof. Dr.-Ing. Christof Breckenfelder received his Diploma in electrical engineering in 1997 from the Technical University of Berlin and received his Ph.D. at the University of Bremen in 2011. He became a professor for the University of Applied Sciences Niederrhein (Hochschule Niederrhein) in Mönchengladbach, Germany in 2013 for the Faculty of Textile and Clothing Technology with a focus in computer modeling and simulation of textile products.
    Dr.-Ing. Christoph Greb received his Diploma in mechanical engineering in 2008 from RWTH Aachen University and completed his Ph.D. summa cum laude in 2013 also at RWTH Aachen. He is currently the head of the composites division and scientific director for the Institute of Textile Technology in Aachen, Germany

  • The objective of the presented work is to take advantage of the precision capabilities of tailor-fiber-placement (TFP) embroidery processes in order to qualify carbon-fiber parts as viable antennas for wireless power transfer applications in multifunctional carbon-fiber-reinforced plastic (CFRP) composites. The solution comes first from a literature study of electrical, high-frequency, and textile engineering concepts. This review built familiarity with the technological challenges and state-of-the-art of the presented technology. Next step was iterative experimentation of machine capabilities for the production of carbon-fiber antennas. Finally, antenna prototypes were produced and their physical and electrical characteristics were evaluated through several test methods. The results showed that TFP embroidery machines were capable of producing quality, carbon antennas. Induction values of the antennas from 0.5 to 3.5 'H were achieved. Signal transfer efficiencies from carbon-antenna transmitters to an aftermarket receiver show promise in commercial application.
