This Ph.D. thesis is focused on the energy supply of communicating electronic microsystems. The ultimate goal is to make them autonomous by harvesting energy coming from the ambiant environment. In particular, we explored a scavenging way based on temporal variations of temperature. Those variations are, by nature, slow (some degrees during several hours) which excludes nearly all "classical" solutions. To solve this problem, we developped a new approach, coupling magnetic and piezoelectric materials. This hybridization is able to overcome the temporal dependance and to generate peaks of energy of several tens of μW when crossing some thermal thresholds. To conclude this work, we turn our attention to the global simulation of this phenomena...
