We here describe a thin, highly stretchable transparent and molecular permeable porous electrode with a well-defined honeycomb structure fabricated by a combination of a bottom-up breath figure process and top-down sputtering of metals. Furthermore, the honeycomb electrode–hydrogel hybrids show higher durability, optical transparency, and electrical conductivity. The optical and electrical properties of the electrode, and its potential for use as a stretchable transparent electrode, are discussed.
