Abstract
A variable stiffening device that include a first electrode structure and a second electrode structure. The first electrode structure includes an electrode extension that extends into a cavity defined between an electrode of the first electrode structure and an opposing electrode of the second electrode structure. The first and second electrode structures may be arranged in a load-bearing state by applying a voltage thereto to electrostatically attract the electrode to the opposing electrode to press the electrode extension within the cavity. Friction between the electrode extension and engaging surfaces defining the cavity prevent the electrode extension from slipping within the cavity, thereby maintaining a structural relationship among the components of the first and second electrode structures in response to an application of a load to the variable stiffening device.
