Abstract: A supercapacitor-like device is described that uses a porous, conductive foam as the electrodes. After the device is charged, an explosive wave front can be used to remove electrolyte from the metal foam. This creates a large net charge on each electrode, which will readily flow through a load placed across the electrodes. The removal of charge can potentially occur on a time scale of microseconds, allowing a supercapacitor to be used in pulsed power applications. The creation of this net charge requires significant energy, meaning this concept may also be suitable for removing kinetic energy from objects.

Abstract: Rotary motion devices (10) are provided. In one embodiment, the rotary motion devices (10) may comprise: a mass (12); a circumferential component (14); a plurality of spokes (16) connecting the mass (12) to the circumferential component (14), at least one of the spokes (16) comprising an electroactive polymer, wherein: the at least one spoke (16) has at least one input electrode and is configured to deflect upon application of an electrical potential across the at least one input electrode, and the rotary motion device (10) is configured such that deflection of the at least one spoke (16) causes the mass (12) to move, thereby causing the rotary motion device (10) to become off balance with respect to gravity, and rotate.
