Abstract:
1. A volume and/or shape memory system comprising: (a) an energy transducing member; (b) a carrier, wherein the energy transducing member is carried by the carrier and movable relative thereto; (c) one or more nanoporous materials contained within the carrier and providing nanopores; and (d) one or more solutions contained within the carrier, wherein the solution is in contact with the nanoporous material and the energy transducing member, the solution being saturated or supersaturated with a solid temperature-sensitive compound, such that temperature changes in the solution result in precipitation or dissolution of the solid temperature-sensitive compound, thereby changing an ion density at the interface between the nanoporous materials and the solution, and wherein a temperature change to the solution affects the wetting of the one or more nanoporous materials and causes the solution to enter or exit the nanopores thereof to effect movement of the energy transducing member.
