How can we optimize energy harvesting in closed, confined environments? Adrien Morel's work on power management for piezoelectric harvesters is proof that CEA-Leti is leading the race to meet the increasing demand for energy autonomy in embedded systems in inaccessible environments. 

After his first internship in our labs, focusing on piezoelectric materials, Adrien decided to extend his work during his thesis. His thesis studies involved electrically tuning the resonant frequency of a piezoelectric vibration energy harvester in order to monitor its dynamics in real time. After comparing different combinations of power harvesting strategies, Adrien implemented the most effective one in a dedicated integrated circuit.
 
The bandwidth of the harvester has been increased by up to six times compared to the traditional approaches in the literature.
 
Adrien is paving the way for more autonomous, energy-efficient systems in closed, confined environments. He has also pointed out that applications are diverse, and not always where we expect them to be! For example, this breakthrough could improve the living conditions of patients wearing medical devices in need of a constant energy supply, as it will enable energy-efficient autonomy without the need for further invasive intervention. No need to replace batteries! 

"One of the Leti's biggest strenghts is that as researchers, we get the opportunity to work on interdisciplinary domains, which means we get to exchange ideas with so many people. It is rewarding, and I think it is unusual to benefit from this kind of working dynamic", he says. 
 
But it was also a challenge for him to collaborate with so many people and to gather enough information to complete his thesis successfully! This was actually the main reason he won this prize.
