Abstract

Inspired by biological cilia used for nutrient transport, locomotion or sensing, researchers fabricated artificial counterparts that are supposed to perform equivalent tasks. Previous studies have primarily focused on the ability of an artificial cilium regarding fluid transport. In contrast, our study focuses on the sensing ability, and in a first step, the oscillation modes and the associated resonance properties were investigated. Magnetizable artificial cilia were devised and fabricated using poly(dimethylsiloxane) enriched with Iron(II,III) oxide nanoparticles. The resulting composite material simultaneously features elasticity and magnetic properties and thus, the movement of the cilium can be evaluated using an electromagnetic pickup. Experiments show a decreasing oscillation frequency with increasing distance between pickup and cilium which converges towards 5 Hz at large distances. By using digital image processing, the natural frequency of the cilium without interaction with a magnetic field was evaluated to be 5.29 Hz and matches the data obtained by simulation and calculation.
