Prized for their power and durability, micro-supercapacitors have not yet established themselves as a power source for the Internet of Things (IoT). The lack of solid electrolytes, which allow 'fast' conduction of ions, is at the root of many practical problems. A team from IEMN, UCCS and UCLA has developed the first photostructured solid-state micro-supercapacitor. Each step of the technological manufacturing process was carried out using standard equipment from the microelectronics industry. This work brings us closer to an industrial transfer of micro-supercapacitors.
