The present invention generally provides devices and methods involving electrochemical actuation. The devices may comprise at least one component capable of exhibiting a volumetric or dimensional change upon application of a voltage. In some cases, the volumetric or dimensional change may produce mechanical work. Some embodiments of the invention may provide devices capable of exhibiting high actuation rates and supporting high amounts of stress (e.g., in tensile and/or compressive loading). In some embodiments, the present invention may provide morphing structures that may be useful in applications such as airfoils.
