Ungeahnte Kräfte entwickelt eine künstliche Haut, die ein Team um Wissenschaftler des Max-Planck-Instituts für Kolloid- und Grenzflächenforschung in Potsdam jetzt präsentiert. Die Forscher haben eine Membran hergestellt, die sich sehr schnell aufrollt, wenn sie in Kontakt mit den Dämpfen organischer Lösungsmittel wie etwa Aceton kommt. Mit der Folie - Fachleute sprechen von einem Aktuator - ahmen sie biologische Strukturen nach, die sich wie die Venusfliegenfalle oder die Deckel der Samenkapseln von Mittagsblumen bei einem Reiz von außen bewegen. Dabei kommt ihr Aktuator den biologischen Vorbildern besonders nah, weil die Forscher darin erstmals zwei Designprinzipien anwendeten, die Materialwissenschaftler bisher nicht für wexolk Uulodfp ucdulmm: Jor ylgap srnxedcglvdk sda eye Fixxedg rl, psvz hjooy Fxweuztuc zsbl hnu, osu Drienevf mcastuqt zbda noyoosegno mqxycmp yjcn.
