One of the last remaining unshrinkable obstacles blocking the progress of fully integrated, wearable technology is the clunky component that absorbs and disburses stray electricity and converts alternating current from a power source into the direct current used by most devices. Due to a meager selection of materials that can perform those diverse functions, these components — called electrolytic capacitors — tend to be a limiting factor when it comes to downsizing electronics. But a breakthrough by materials science and engineering researchers at Drexel University and Sungkyunkwan University in Korea could eventually replace them with a capacitor so thin and flexible that it’s literally painted on.
