Rolled-up island-bridge (RIB): a new and general electrode configuration design for a wire-shaped stretchable micro-supercapacitor array

The “rolled-up island-bridge” design enables the wire-shaped stretchable micro-supercapacitor array to achieve a high linear/areal energy density (7.94 μW h cm⁻¹/7.22 μW h cm⁻²), large elongation (100%), and stable and tunable electrochemical output.
