Abstract
A device for generating a second temperature variation ΔT2 from a first use temperature variation ΔT1, includes an elastocaloric material layer, having an internal temperature which is able to vary by ΔT2 in response to a given mechanical stress variation Δσ applied to the elastocaloric material layer. The variation Δσ being induced by the first use temperature variation ΔT1 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 ΔT1. The suspended element is arranged so as to make the mechanical stress applied to the elastocaloric material layer vary by Δσ in response to the temperature variation ΔT1, to generate the second temperature variation ΔT2.
