1. A method of actuation, comprising:

  • applying a voltage or current to an actuator including a negative electrode, a positive electrode, and a species formulated to intercalate with or de-intercalate from at least one of the electrodes, the applied voltage or current inducing intercalation or de-intercalation of the species in at least one of the negative electrode and the positive electrode, whereby the intercalation or de-intercalation induces a volumetric or dimensional change of the actuator and linear strain is produced, wherein the volumetric or dimensional change induces a bend or twist in the actuator.
