Best poster for his FDN 2022 DNA Nanotech breakthrough

Ludwig Rotsen wanted to draw inspiration from life to create advanced nanotechnologies, and he has done an excellent job addressing his goal, confirming CEA-Leti’s focus on always reinventing innovation based on available resources and on demand.
 
After completing of the first part of his thesis in Montpellier, France, Ludwig Rotsen joined CEA-Leti to work on DNA origami for use in lithography, in collaboration with the CNRS. 
 
The versatility and addressability of DNA are unprecedented, making it possible to broaden our catalog of 2D networks and to envision increasingly specific uses that will require nanostructures. This high addressability and the limited quantity of lithographic material mean that it is possible to generate countless structures in a relatively short timeframe (in the order of several weeks).
 
Thanks to the new process for depositing DNA nanostructures on silicon dioxide, Ludwig controls every 2D network interaction, and his work will enable great strides in the field of quantum computers.
 
Ludwig notes “𝑺𝒊𝒏𝒄𝒆 𝑰 𝒂𝒎 𝒘𝒐𝒓𝒌𝒊𝒏𝒈 𝒐𝒏 𝒂 𝒎𝒖𝒍𝒕𝒊𝒅𝒊𝒔𝒄𝒊𝒑𝒍𝒊𝒏𝒂𝒓𝒚 𝒔𝒖𝒃𝒋𝒆𝒄𝒕, 𝑰 𝒘𝒆𝒂𝒓 𝒕𝒘𝒐 𝒉𝒂𝒕𝒔—𝒕𝒉𝒂𝒕 𝒐𝒇 𝒂 𝒑𝒉𝒚𝒔𝒊𝒄𝒊𝒔𝒕 𝒂𝒏𝒅 𝒕𝒉𝒂𝒕 𝒐𝒇 𝒂 𝒄𝒉𝒆𝒎𝒊𝒔𝒕. 𝑰 𝒄𝒂𝒏’𝒕 𝒂𝒍𝒘𝒂𝒚𝒔 𝒈𝒊𝒗𝒆 𝒂𝒅𝒗𝒊𝒄𝒆 𝒐𝒏 𝒗𝒆𝒓𝒚 𝒔𝒑𝒆𝒄𝒊𝒂𝒍𝒊𝒛𝒆𝒅 𝒕𝒐𝒑𝒊𝒄𝒔 𝒊𝒏 𝒆𝒊𝒕𝒉𝒆𝒓 𝒐𝒇 𝒕𝒉𝒐𝒔𝒆 𝒇𝒊𝒆𝒍𝒅𝒔, 𝒃𝒖𝒕 𝑰 𝒂𝒍𝒘𝒂𝒚𝒔 𝒉𝒂𝒗𝒆 𝒂𝒏 𝒐𝒑𝒑𝒐𝒓𝒕𝒖𝒏𝒊𝒕𝒚 𝒕𝒐 𝒍𝒆𝒂𝒓𝒏 𝒔𝒐𝒎𝒆𝒕𝒉𝒊𝒏𝒈 𝒏𝒆𝒘!”
 
Both his greatest challenge and what he has most enjoyed has been participating in a project for two organizations that have different approaches. Working at CEA-Leti has taught him to better understand real-work applications for his thesis, along with issues around the transfer of his innovation to the industry market. 
 
To close, his experience reminds us that sometimes, reorganizing what exists is a way of finding innovative solutions for tomorrow’s technologies.



Best Thesis award from the EEA Club 2022

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.
