Abstract
Devices and methods for providing electrochemical actuation are described herein. In one embodiment, an actuator device includes an electrochemical cell including a negative electrode and a positive electrode At least a portion of the negative electrode is formed with a material formulated to at least one of intercalate, de-intercalate, alloy with, oxidize, reduce, or plate with a first portion of the positive electrode to an extent different than with a second portion of the positive electrode such that a differential strain is imparted between the first portion and the second portion of the positive electrode and such that at least a portion of the electrochemical cell is displaced. The electrochemical cell includes a portion that is pre-bent along an axis of the electrochemical cell to define a fold axis and the displacement of the at least a portion of the electrochemical cell is maximized along the fold axis.
