1. An electrochemical actuator, comprising:
- a. a negative electrode;
b. a positive electrode; and
c. an intercalating species;
wherein, when said electrochemical actuator is subjected to an applied voltage or current, or is permitted to discharge from an initially charged state, intercalation or deintercalation of said species in at least one of the electrodes of said actuator results in a volumetric or dimensional change of said actuator and linear strain of at least 1% is produced.

Abstract
The present invention provides devices and structures and methods of use thereof in electrochemical actuation. This invention provides electrochemical actuators, which are based, inter-alia, on an electric field-driven intercalation or alloying of high-modulus inorganic compounds, which can produce large and reversible volume changes, providing high actuation energy density, high actuation authority and large free strain.
