Flexible electrochemical electrodes are a type of electrode material and device that can stably perform electrochemical functions (charge transfer, electrochemical reactions, molecular detection, etc.) under deformation conditions such as bending, folding, stretching, and twisting. It breaks through the defect of traditional rigid electrodes being "hard, brittle, and vulnerable", and is the core upstream material of the flexible electronics industry.
