A team of researchers from MIT’s Tangible Media Group developed Cilllia, a computational method of producing extremely fine, 3D printed hair-like structures and finds cutting edge applications for them. Cillia can be used to 3D print hair-covered, low-friction materials that will turn any surface covered with them into actuators when exposed to specific vibrations. The hair in these materials will move objects along specific paths that have been built into the geometry of the hair. The hair-covered materials can also be used as a rotary motor, a linear motor or a combination of the two. These motors work only by applying specific vibrational frequencies to the materials, and they don’t use any gears or moving parts.
