Produced through a process of 3D printing with polymers—altogether referred to as “4D printing” because of its core of programmable, shape-shifting material—rapidly developing microneedles may replace painful hypodermic needles in the next decade. Professor Howon Lee, who has lead the research from Rutgers University, has filed a patent on this new technology, which produces hollow needles that are barbed, much like the stinger of a …
