Printed electronics open way for electrified tattoos and personalized biosensors

Article note: Typical academic PR behavior. Bombastic largely-irrelevant headline, dumb demo video of a parlor trick that could be accomplished with a $10 trace pen, then wayyy buried, a method for printing three jettable materials that don't require high-temperature or caustic post-processing to make printable functioning (albeit shitty) transistors. Because the hype is much more important than the meaningful research.
