Abstract

A highly transparent and stretchable electrode based on a Au nanomesh, electrodeposited with a thin layer of MnO₂ with a transparency of 84.7% is introduced. The as-prepared transparent, stretchable, and imperceptible supercapacitor (TSPS) exhibits a specific capacitance of 0.53 mF cm⁻² and excellent bending stability, together with high stretchability (up to 160% strain).
