Stellantis

Innovation plays a vital role in Stellantis’ growth policy and means being able to quickly bring to market a wide range of products that meet customer requirements in terms of quality and safety while respecting the environment. One of the objective of its Scientific Department is to animate research on topics such as nanotechnologies, mechanical and material innovation, ensuring the acquisition and the control of scientific knowledge required for its activities, to explore breakthrough technologies that could have a future in the automotive product and develop methodologies with high-level scientific content to contribute to the future development of innovative products.

The aim of this project for PSA is the development MEMs technology that will allow to their designers to get real time tools for modifying rapidly prototype with simple CAD modification. It would reduce the time of vehicle design and would give them a competitive advance. Furthermore, the MEMS technology could find applications in automotive industry where real time answers are necessary to manage behavior. Comfort and Aerodynamic are two examples.

During the first step of the project, PSA’s engineer Stéphane Delalande has participated to the conception of the MEM unit cell. His skills in material science has allowed to focalize, in collaboration with FEMTO-ST, on a design compatible with collaborative motions of the MEMs. They are jointly preparing a patent on the design of the MEMs. Few publications were realized on the topics.

As mentioned above, the potential for applications is real. However, we are still far such real applications. Once the proof of concept has been realized on at least two elements, the next and not least difficult step, should be to develop the technology necessary to launch its mass production.
