Zero-power autonomous devices will abound on the IoT of the future, and battery manufacturers are scratching their heads to come up with the best possible solution ensuring high energy and power density at miniature scale. A new material developed recently at Finland-based VTT shows promise, based on energy and power density of a supercapacitor depending on the surface area and conductivity of the solid electrodes. The size? So small it fits inside an IC.
