Abstract: A device for generating a second temperature variation ?T2 from a first use temperature variation ?T1, includes an elastocaloric material layer, having an internal temperature which is able to vary by ?T2 in response to a given mechanical stress variation ?? applied to the elastocaloric material layer. The variation ?? being induced by the first use temperature variation ?T1 There is a suspended element in mechanical contact with the elastocaloric material layer so as to apply to this layer a mechanical stress that varies in response to the use temperature variation ?T1. The suspended element is arranged so as to make the mechanical stress applied to the elastocaloric material layer vary by ?? in response to the temperature variation ?T1 to generate the second temperature variation ?T2.
