High-performance, flexible, solid-state micro-supercapacitors based on printed asymmetric interdigital electrodes and bio-hydrogel for on-chip electronics

Rapid development of miniature, portable and highly integrated electronics increases the demand for micro-sized power sources and on-chip energy storage units; micro-supercapacitors with in-plane electrode finger arrays are developed for this purpose. This study fabricates flexible, solid-state, interdigital micro-supercapacitors with MoO3-x nanorods as cathode fingers and glucose-derived activated carbon nanospheres as anode fingers via a...
