South Korean scientists have made a durable super-stretchable, twistable ac electroluminescent light emitter. The secret is mechanically-reinforced ionogel conductors, according to Pusan National University, where the emitter was developed. “We developed stretchable and durable conductive ionogels with a double-network structure, which is achieved by combining stretchable soft polymer network with stress-resistive hard polymer network,” said researcher Jinhwan ...
