Diatoms - the source of biotribological inspiration for novel 3D MEMS — Ille C. Gebeshuber1 and •Richard M. Crawford2 — 1Institut für Allgemeine Physik, Technische Universität Wien, Wiedner Hauptstrasse 8-10/134, 1040 Wien, Austria & Austrian Center of Competence for Tribology, Viktor Kaplan-Strasse 2, 2700 Wiener Neustadt, Austria — 2Alfred-Wegener Institute for Polar and Marine Research, Bremerhaven, Germany
Diatoms are single-celled organisms with rigid parts in relative motion at the micrometre scale and below. They produce interlocked hydrated silica structures with high precision. These micromechanical parts have been evolutionarily optimized during the last 150 million years or more. It is suggested that MEMS/NEMS researchers meet with diatomists to discuss future common research attempts regarding biomimetic ideas and approaches for novel and/or improved MEMS and NEMS with optimized tribological properties [1,2].
