1. A thermal energy scavenger assembly comprising:

  • at least one temperature-sensitive element made of material which exhibits shape memory due to thermoelastic, martensitic phase transformation;

    reaction means reacting with said element for applying a stress to said element to strain said element during a first phase and for responding to the unstraining of said element during a second phase; and

    stress limiting means for limiting the strain of said element during said second phase whereby the strain upon the element may be greater during the first phase than during the second phase.
