3D-Printed Hair Structures for Actuation and Sensing

Hair has many functions such as to provide warmth, adhesion, locomotion, sensing, and a sense of touch. Researchers from MIT Media Lab's Tangible Media Group introduce a computational method of 3D printing hair structures. They can design and generate hair geometry at 50 micrometer resolution and assign various functionalities to the hair. The ability to fabricate customized hair structures enables them to create super fine surface texture, mechanical adhesion, and new passive actuators and touch sensors on a 3D printed artifact.
