“Our innovations in sensor design, biocompatible ink, and high-speed printing pave the way for future on-body manufacturing of electronic tattoo sensors,” says Nanshu Lu, one of the lead researchers at the University of Texas at Austin. “It has broad applications both within and beyond clinical settings.”
The invention, detailed in the journal Cell Biomaterials, is being heralded as a potential game-changer, not just for brain monitoring but for the growing field of brain-computer interfaces—the futuristic devices that let people control machines with their thoughts.
