1. A method for cooling comprising:
(a) applying an electric or magnetic field to a first member, such that a first material of the first member increases in size in response to the applied field and stresses an elastocaloric material of a second member mechanically coupled to the first member; and
(b) after (a), removing the electric or magnetic field from the first member, such that the first material returns to its size prior to (a), thereby releasing stress on the elastocaloric material from the first material,
wherein the releasing stress of (b) causes the elastocaloric material to absorb heat.
