At Sungkyunkwan University in Seoul, materials scientists have long wrestled with a quiet paradox at the heart of organic semiconductors: materials that are cheap, flexible, and light enough to reshape electronics, yet stubbornly poor at conducting the electricity that would make them useful. Professor Kang Bosoek's team has now resolved two of the deepest obstacles simultaneously — coaxing charge into these polymers at near-theoretical limits, and then building molecular pathways so that charge can actually travel. The work suggests that the flexible, wearable, sensing devices long imagined a
