Abstract: A cooling system employs at least one composite elastocaloric device. Each composite device has a first member with a first material and a second member with an elastocaloric material. The first material increases in size in response to an applied electric or magnetic field and returns to its prior size upon removal of the applied electric or magnetic field. The first and second members are mechanically coupled together such that the increase in size of the first material applies a stress to the elastocaloric material and the return of the first material to its prior size releases said stress, thereby causing the elastocaloric material to absorb heat.
