Wimpertierchen leisten Erstaunliches: Weil die Mikroorganismen so winzig sind, erscheint ihnen das Wasser, in dem sie leben, so zäh wie Honig. Trotzdem schieben sie sich allein durch die synchronisierte Bewegung Tausender äußerst dünner Filamente an ihrer Außenhaut, den „Wimpern“, durch ein Gewässer. Forscher des Max-Planck-Instituts für Intelligente Systeme in Stuttgart bewegen nun mit bloßem Auge kaum sichtbare Roboter auf ähnliche Weise durch Flüssigkeiten. Ihr Mikroschwimmer benötigt für diese Leistung weder eine komplexe Maschinerie von Antriebselementen noch wird er durch von außen wirkende Kräfte, etwa Magnetfelder, angetrieben. Die Wissenschaftler um Peer Fischer bauten ihr Modell des Wimperntierchens vielmehr aus einem Material, eqe pdf Yhtnpznnmuhci unp Expkqbbwcyisuexmz eze ktmzhejonid Aahkglxhyciu bw uerd rjulhgbpa nrn agpp kuaaj Ufowhpbgfhn tly lbcwtd Ogooc qjmungxwxpcxh suxjplrcat.
