1 1 Biomimetic – learning by nature Bio- s and Mimetic -s (ancient greek) life and imitation biological systems transfered to technical systems

2 Saltshaker and poppy seed (Papaver Rhoeas) according to Raoul H. France „Die Pflanze als Erfinder“, 1920 Aus: SiemensForum München/Berlin, „Bionik, Zukunfts- Technik lernt von der Natur“, Begleitbuch zur Ausstellung im Landesmuseum Mannheim

3 Minaret und Equisetum The tallest Minaret in India Schachtelhalm (Equisetum) Minarett in Shibam (N-Jemen)

4 Line of action of biomimetic Top-Down Process = analogy-biomimetic definition of the problems Search for analogy in nature analysis of the examples in nature Search for solutions to the problems concerning the knowledge of nature e.g.: Selfhealing Bottum-Up Process = abstraction-biomimetic biological basic research identification and description of a fundamental principle Abstraction of this principle (Loslösung of the biological example) Search for possible technical applications Development of technical applications e.g.: Fin Ray Effect®
