Chemical and Engineering News (Oct. 3) – Artificial limbs don’t offer the sense of touch that connects us with loved ones or allows us to enjoy the silky feel of a fabric. Researchers working on stretchy, large-area electronics hope to mimic at least some of the critical sensing features of real skin – and add new ones, such as displays that “blush” to communicate emotion. Former Illinois materials scientist John Rogers is interested in electronic skin for medical applications that require smaller, tattoolike patches instead of large swaths to wrap prosthetics or robotics.
