MITs Hairy Metamaterial

Researchers at MIT have developed yet another unusual metamaterial, and this one is simply hair. We’ve seen some experiments in 3D printed hair previously, but those were essentially for fun and artistic merit. Those experiments used extrusion movements to pull strands from the nozzle, leaving thin and flexible hair-like structures that could be rearranged at…

A newly invented process could enable large-scale use of nano-printed metal materials. 3D printing is most often done at a visible scale, but for many years researchers have sought methods of printing materials at a nano scale to take advantages of molecular effects and microscopic structures. While many of these experiments have been successful, the…
