This concise textbook introduces a systems approach to technology, describing tribological, mechatronic, cyber-physical systems, and the technologic concept of Industry 4.0 to students in a range of engineering domains. "Technology" in this book refers to the totality of human-made, benefit-oriented products, based on engineered combinations of material, energy and information. Dr. Czichos examines technology in this volume in the context of systems thinking with regard to the following main technology areas

• Technical systems with "interacting surfaces in relative motion" especially in mechanical engineering, production, and transport; including the analysis of friction-induced energy losses and wear-induced materials dissipation.
• Technical systems that require a combination of mechanics, electronics, controls, and computer engineering for needs of industry and society.
• Technical systems with a combination ofmechatronics and internet communication.
• Cyber-physical Systems for the digitalization of Industry in the development project Industry 4.0.
• Considers technology as combination of the physical world and the digital virtual world of information and communication.
• Describes the product cycle of technical systems and the corner stones of technology: material, energy and information.
• Presents a holistic view of technology and engineering.

Autorentext

Horst Czichos graduated in Precision Engineering and worked as design engineer in the optical industry. He holds degrees in Physics (FU Berlin) and in Materials Science (TU Berlin) and received from the University of Leuven an honorary doctorate for his interdisciplinary research in tribology. He was President of BAM (1992 to 2002), and of EUROLAB. Currently, he is Professor for Mechatronics at the University of Applied Sciences, BHT Berlin. In his publications, Dr. Czichos emphasizes the significance of systems thinking in science and technology. In 2013 he published a book on the triad Philosophy - Physics - Technology, which appeared as English Edition under the title "The Word is Triangular" (Springer 2021).
