We report a strategy to increase the linear stroke of nanoporous gold (npg) electrochemical actuator, by incorporating solid and parallel gold layers into npg and form Au/npg multilayer composites. The actuation strokes in the direction perpendicular to layer planes are larger than the rule-of-mixture predictions and can be 20% greater than that of monolithic npg; meanwhile, the multilayer composites are stiffer than the npg monolith. Current study provides an approach to simultaneously increase the actuation strain, the effective stiffness, and mechanical stability of actuation material, and thus global performance of np solid actuator.
