New technologies inspired by the ancient art form called origami have lead in recent years to advances in various industries, including medical technology. The results include new kinds of batteries based on origami techniques like those developed by ASU researchers, including Hanqing Jiang, a former Fulton Schools professor of mechanical and aerospace engineering. Based on a form of origami called kirigami, Jiang and two doctoral students developed a method of cutting and twisting to produce interlocking structures of lithium ion batteries that can be stretched. The prototype battery, sewn into an elastic wristband attached to a smart watch, powered the watch and its functions – including playing videos.
