Bionik und Nachtfalter: Was können wir von Insekten über Tarnung und Unsichtbarkeit lernen?

Der Vortrag geht auf die vielfältige Forschung an Nachtfaltern im Bereich der Bioakustik, und welche Anpassungen den Insekten helfen um der nächtlichen Jagd durch Fledermäuse zu entgehen. Diese Anpassungen bieten spannende Ansätze zur Entwicklung von bionischen Schallabsorbern, die sich durch ein anpassbares Frequenzspektrum und vielversprechende Platzersparnis auszeichnen. Durch biologisch inspirierte Metamaterialien auf Basis der Nachtfalter-Flügel können neuartige akustische Konzepte erschlossen werden. Aus der Forschung an den biologischen Metamaterialien entstand die Idee zu einer neuartigen Methode, dem "twinning". Mit dieser Methode können die Eigenfrequenzen von unterschiedlich geformten Körpern (z.B. Trommeln) so angepasst werden, dass sie denselben Klang erzeugen. Die Grundlage dafür bietet die Verwendung von Metamaterialien zur Erzeugung von anisotropen, heterogenen Materialeigenschaften, wie sie auch im Fachbereich von "cloaking" eingesetzt werden.
