Abstract
Deformable electrodes, deformable supercapacitors comprising the deformable electrodes, and electric circuits comprising the supercapacitors are provided. Methods of using the supercapacitors to convert mechanical energy to electrical energy are also provided. The supercapacitors include a liquid electrolyte disposed between two electrodes, at least one of which is reversibly deformable when it is compressed. The liquid electrolyte is infused into the deformable electrode and the supercapacitors are characterized in that the deformation of the deformable electrodes causes the interfacial area between the electrolyte and the deformable electrode to decrease when the electrode is deformed.
