An international team of researchers (Saudi Arabia, USA – Georgia Institute of Technology) has demonstrated transistor‐level integration of electrochemical microsupercapacitors and thin film transistor rectifiers using ruthenium oxide as the common electrode material connecting all devices in the microcircuits. Thin film rectifiers are shown to be capable of rectifying AC signal input from either triboelectric nanogenerators or standard function generators. They exhibit exceptionally slow self‐discharge rate and sufficient power to drive various electronic devices. The study opens a new avenue for developing compact on‐chip electrochemical micropower units integrated with thin film electronics, simplifying device fabrication and realizes significant miniaturization of self-powered sensor devices…read more.
