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

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 = Bottum-Up 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 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®

5 Today`s topics Fin Ray Effect® Self-healing Lotus-effect® Petal-effect
Folding
