Researchers grow artificial hairs with clever physics trick
Things just got hairy at Princeton. Researchers found they could coat a liquid elastic on the outside of a disc and spin it to form useful, complex patterns. When spun just right, tiny spindles rise from the material as it cures. The spindles grow as the disc accelerates, forming a soft solid that resembles hairs. Published in PNAS Feb. 22 (2021-02-22)
