    摘要： An energy harvesting system comprises a first region and a second region having a temperature difference therebetween. A heat engine is configured for converting thermal energy to mechanical energy. The heat engine includes a first discrete element of a shape memory alloy having a crystallographic phase changeable between austenite and martensite in response to the temperature difference between the first region and the second region. The first discrete element of the shape memory alloy expands and contracts in response to the phase change to exert a linear force. A motion conversion mechanism is operatively connected to the first discrete element to be driven by the linear force and a component is driven by the motion conversion mechanism.

    摘要： A device is provided that may be adapted to control or monitor the pressure level of a fluid system. The device includes a member composed of a shape memory alloy in a superelastic state. The member is configured to undergo a phase change from a high modulus Austenitic phase to a low modulus Martensitic phase and stretch in response to an activation stress. In one embodiment, the member defines two ends such that one end of the member is operatively connected to a fixed point. Another end of the member is operatively connected to a movable element. As the member stretches in response to the activation stress, the movable element is translated relative to the fixed point. In another embodiment, the member includes two plates with respective holes that are selectively aligned when the first and second plates stretch or deform in response to the activation stress.
