MacLeans (blog, Feb. 17) -- John Rogers, of the University of Illinois at Urbana-Champaign, is working on electronics that can integrate into the body and are even water soluble. His team has found a way to reduce wafers to tiny, flexible “nanoribbons.” (He says it’s like comparing the rigidity of a plank of wood to the bend in a sheet of paper.) By bonding nanoribbons to stretchy rubber, his team can create electronics with “skin-like properties,” biocompatible, and even dissolveable.
