“…In our previous works, we employed elastomer dispersed with magnetic particles. We developed energy harvesting systems [1][2][3], artificial cilia [4][5][6][7][8][9][10][11][12][13][14] and worm-like robots [15,16] using the magnetic soft material. We evaluated the motion of worm-like crawling robots and found that the interface between the robot and the substrate affected so much for the locomotion ability of the robot [15].…”

“…If we could apply biomimicry structures of these natural cilia, they would be useful engineering tools. We utilized magnetic elastomer [7][8][9] to mimic the motion of flexible structures in natural cilia [10][11][12][13][14][15][16][17][18][19][20].…”

Recently, many researches on biomimetics have been reported, in which soft motions of natural creatures have also been targeted. Among them, cilia are attracting natural soft organ, which is an effective fluidic system in the natural world. Cilium is a simple hair-like organ; however, it works in a non-simple way. For example, beating pattern of natural cilium consists of 2 types of different stroke patterns; effective stroke and recovery stroke. We focused on a cilium as our target as a simple cantilever of a soft elastic material. We have already developed artificial cilia with magnetic elastomers. In this research, we compared cantilever beams with soft-and hard-magnetic particles. In this paper, we performed 2 experiments to compare the characteristics of cantilevers with 2 types of magnetic powders. In the first experiment, we utilized neodymium magnets that could be controlled the angle in order to observe the motion of beams in the static state. The latter one, we actuated beams in rotating magnetic fields to obtain dynamic behavior of an artificial cilium. As a result, we showed some differences between soft-and hard-magnetic materials.

“…The magnetic elastomer is composed of polymer material dispersed with magnetic powder, which is a functional materials used for actuator, control of visco-elastic properties, and power generation [20][21][22]. We already proposed this new printing system [23,24]. Figure 1 shows a simple schematic of the proposed system.…”

In this paper, we developed a new 3D-printing system for magnetic elastomer, and demonstrated to fabricate artificial cilia. Natural cilia are hair-like organ found in nature. They are effective fluidic system in the natural world that are widely observed on surfaces of microorganisms of creatures, such as Paramecium and throat surface of mammals. Recently, the motion of cilia has been analyzed and mimicked for developing soft actuator, for example, some studies on artificial cilia driven magnetically have been reported. They are small soft actuators, and there are various manufacturing methods for these actuators depending on materials and products. Among them, authors have already developed the concept of a printing system that not only forms a three-dimensional object but also prints out the deformation of the structure. This system can fabricate various shapes of soft actuators without any assembly. In this report, we utilized UV-curable urethane acrylate as a more flexible material than that used in the previous reports, and fabricated artificial cilia by the printer. We set magnetic anisotropy to each cilium and mimicked a metachronal wave, sequential action of plural cilia that causes effective flow.
