EUROPEAN COOPERATION IN SCIENCE AND TECHNOLOGY Proceedings of the COST Strategic Workshop Principles and Development of Bio-inspired Materials 13-15 April 2010, Vienna, Austria Edited by Stefanie E. Tschegg and Robin Seidel About COST COST is an intergovernmental European framework for international cooperation between nationally funded research activities. COST creates scientific networks and enables scientists to collaborate in a wide spectrum of activities in research and technology. COST Activities are administered by the COST Office.

Preface Bio-inspired materials are becoming of increasing interest in many fields of practical applications. In contrast to man-made materials natural materials such as wood, bone and shell are composed of only limited number of basic components. They gain their diversity in mechanical properties by hierarchical structuring and functionalizing of surfaces and interfaces. This allows them to fulfill and to combine a variety of mechanical and additional functions e.g. combining high stiffness and toughness, benign fracture behavior, self-healing, self-adaptability, optical functions, etc. Due to the quickly advancing physical and chemical characterization techniques our knowledge of natural structures and materials has increased significantly in recent years and the secrets of form-structure-function relationships are slowly unveiled. New simulation and production methods allow for the first time to structure technical materials similar to the biological templates. But combining the knowledge of natural materials with modern techniques of simulation and the fabrication of smart technical materials is still the exception due to the lack of communication between bio- and engineering- and material scientists. In order to close this gap, a COST Strategic Workshop, was believed to be the most suitable. High-ranking representatives of natural science, medicine and industry were invited to report on the latest state of knowledge and young researchers were asked to participate and present their own work in the form of poster. With this, the objectives of the workshop were defined as: • Researchers and decision makers from different disciplines, such as Biology, Physics, Chemistry, Materials Science, Medicine, Biomimetics and interdisciplinary fields, should discuss forefront topics, which can be used in the future development of bio- inspired materials. • They should explore the state of knowledge and identify present lack of knowledge as well as demands on specified properties of new materials. They should identify new and promising technologies to develop new bio-inspired materials. • The Strategic Workshop should address needs for interdisciplinary research and try to establish and promote multidisciplinary scientific cooperation in these fields. The following forefront topics were identified: • What are the main topics of today´s research on bio-based materials in the different European countries and research groups? • Which demands on special properties of materials exist? Which developments seem promising using nature as a teacher and thus developing bio-inspired materials? • Which research institutions should cooperate and exchange knowledge, ideas, as well as equipment? As an outcome, the strategic workshop should • raise political awareness of the potential of bio-inspired materials • enhance cooperation at European level • contribute to COST Actions • promote research and cooperation in the field of bio-inspired materials in Europe. The workshop has been organized along four main themes: Overview on existing activities on bio-inspired materials • Properties and characterization of natural materials and strategies of nature • Man-made bio-inspired materials - abstraction and translation • Applications - optimized materials and structures and future demands Stefanie Tschegg and Robin Seidel Chair and co-chair of the Strategic Workshop Vienna, February 2010 Content Invited Speakers Eduard Arzt and Marleen Kamperman Bioinspired Adhesive Surfaces 17 Friedrich G.
