In this paper, a reprogrammable magnetically actuated self-assembled (RMS) cilia array was fabricated which has a simple fabrication process and whose magnetization direction can be modified. To analyze the characteristics of the RMS cilia, samples were prepared, and magnetization and young’s modulus were measured using VSM and the universal testing machine, respectively. First, to measure VSM, one cilium was cut out from the RMS cilia array and used as a measurement specimen. In the case of the universal testing machine, the cilium did not match the testing scale, so the sample was prepared with NdFeB powder, EcoFlex, and hexane in a 1:3:1 weight ratio, which is the ratio used to fabricate the RMS cilia. The results measured using each sample is shown in Figure S1. The magnetization of a cilium was 68,608 A/m and the Young’s modulus (E) of cilium was about 211 kPa.
