Charge-Induced Reversible Bending in Anodic Porous Alumina–Aluminum Composites

Electrical energy can be transformed into mechanical energy in materials such as piezoelectric ceramics, electrostrictive polymers, and carbon nanotubes, because the dimensions of these materials can reversibly expand or contract upon cyclic electrical charging. Recently, charge-induced reversible straining was also observed in nanoporous noble metals, such as Pt, Au, and Au–Pt alloys, which are becoming a promising type of electrochemical actuators for potential applications such as artificial muscles.
