A technological foundation for transparent and ultra-bendable supercapacitors without percolation effects and depth limitations is introduced, with demonstrated examples in in- and out-of-plain ultra-deformation states. This prototype system, built on large-scale interdigitated pattern type electrodes, constitutes significant advances over existing energy systems for optoelectronic systems in terms of electrochemical performance (capacitance ∼405 F g−1) and flexibility (bending radius ∼1.5 mm).
