When I first heard about this development, I thought they were working on something similar to what Bob Langer, a fellow ChemE grad student from MIT, was working on years ago. Normally, all bandaging does is to contain a wound, preventing infection from setting in. That’s why Bob Langer developed his artificial skin to treat burn patients more effectively, because the “new skin” effectively replaced the burned skin and precluded infection in the patient. This new device was being touted as a “smart bandage”. But, that’s not really what Dr. H. Kong (Chemical and Biomolecular engineering, University of Illinois-Urbana), along with Drs. Jeong, Chan, Cha, Zorlutuna, Dyck, Hsia, and Bashir are developing.
