“…For this purpose, we employed silicone elastomer and rubber magnetic material to downsize the robot. Magnetic elastomer could be used for many purposes, for example, dynamic control of the mechanical properties 19) , energy harvesting 20) , and of course various kinds of soft actuators [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] . There have been many reports for bio-mimic approach using magnetic elastomers, such as artificial cilia [27][28][29][30][31][32][33][34] and worm-like robots 33,34) .…”

Recently, many studies on bio-mimic soft robots have been reported. Among living organisms, locomotion of soft bodies, such as snails, worms, and nematodes, have been actively studied. These soft creatures locomote by deforming the muscles of the whole body into waveforms and propagating the waves of the deformation. These locomotion of soft creatures could be applicable to develop a worm-type soft robot which can move in drain pipes and even if in a human body. In this study, we developed worm-like robots which could generate wavy motion under a rotating magnetic field using silicone and magnetic rubber, and investigated its movement characteristics. In addition, based on deformation experiment of a silicone cantilever with a single magnetic element inside made of the same material of worm-like robot, we investigated the effect of the size of the worm robot for further miniaturization.

“…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.

“…In this paper, we demonstrated a new 3D-printing system using magnetic particles for artificial cilia. Natural cilia are known as an effective fluidic device, and the motion of cilia has been researched to realize bio-mimic soft actuators [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Several studies on artificial cilia driven magnetically have been reported [6][7][8][9][10][11][12][13][14].…”

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.
