Super stretchy semiconducting polymers

Silicon has enabled science journalists to cover topics that were once written about only by science fiction authors: implantable sensors, wearable smart gadgets, and even electronic skin. But silicon is naturally more rigid than is desirable for devices that ought to bend and stretch like living tissue. Some scientists have thus turned to semiconducting polymers to create such devices, but these materials have struggled to achieve flexibility without compromising electrical performance. An . . .
