Abstract
A method of cooling includes providing an elastocaloric material; continuously applying a force on the elastocaloric material to cause a continuous mechanical deformation of the elastocaloric material for a predetermined period of time, such that the continuous mechanical deformation creates a solid-to-solid phase transformation in the elastocaloric material; emitting exothermic latent heat from the elastocaloric material to increase a temperature of the elastocaloric material; removing the force from the elastocaloric material upon expiration of the predetermined period of time; and absorbing endothermic latent heat into the elastocaloric material to decrease the temperature of the elastocaloric material and/or an environment adjacent to the elastocaloric material or an electronic/phononic device, etc.
