    摘要： A releasable connection connects a first component to a second component. The second component includes and is manufactured from a Shape Memory Polymer (SMP), and defines a pocket. The first component includes a portion disposed within the pocket. The pocket is deformed from an initial shape permitting insertion of the portion into the pocket to assembly the releasable connection into a connected shape wherein the pocket is deformed to secure the first component relative to the second component. The pocket is transformed from the initial shape into the connected shape by heating the SMP material of the second component to a switching temperature. Re-heating the SMP second component to the switching temperature returns the pocket back to the initial shape from the connected shape to disassembly the releasable connection.

    摘要： An energy harvesting system comprises a first region having a first temperature and a second region. A conduit is located at least partially within the first region. A heat engine configured for converting thermal energy to mechanical energy includes a shape memory alloy forming at least one generally continuous loop. The shape memory alloy is disposed in heat exchange contact with the first region and the second region. The shape memory alloy is driven to rotate around at least a portion of the conduit by the response of the shape memory alloy to the temperature difference between the first region and the second region. At least one pulley is driven by the rotation of the shape memory alloy, and the at least one pulley is operatively connected to a component to thereby drive the component.

    摘要： A heat engine system configured for converting thermal energy to mechanical energy includes a source of thermal energy provided by a temperature difference between a heat source having a first temperature and a heat sink having a second temperature that is lower than the first temperature. The heat engine is configured for converting thermal energy to mechanical energy and includes an element formed from a first shape memory alloy having a crystallographic phase changeable between austenite and martensite at a first transformation temperature in response to the temperature difference between the heat source and the heat sink. The heat engine system also includes a start-up mechanism configured for inducing initial movement of the element in a desired operational direction to thereby start the heat engine.
