Hello and Welcome
At the Flexible Electronics (FEL) Department of Mines Saint-Étienne, our objective is to develop the key technological building blocks enabling complex, flexible, and stretchable electronic components.
We design and manufacture autonomous, ultra-thin, conformable devices, covering energy harvesting and storage, as well as heterogeneous integration on flexible and stretchable substrates. Our work combines thin and flexible materials—such as PI, PET, PC, PaC, and textiles—with high-performance inorganic components, alongside developments in organic electronics (including OECT and neuromorphic devices) and advanced printing technologies.
Application domains include implantable and bioresorbable electronics, electronic skin (e-skin) and wearables, physiological monitoring, smart sensing, human–machine interfaces, IoT, and biorobotics.
Our ambition is to bridge materials science, device engineering, and system integration to deliver electronics that seamlessly interact with the human body or complex environments.

Latest news:
- M2 internship positions (for early 2026) related to soft electronics and circuits
- Engineer or postdoc in the field energy tranmission through skin and implantable electronics
- Engineer or postdoc for fabrication of soft circuit for wearbale chemical sensors
- We are hiring (end 2025 – early 2026) PhD students and postdoctoral researchers in the field of soft electronics for enhanced tactile perception and feedback. See the link for the PhD position. Additional openings (in electronics design, soft circuit fabrication, and haptic feedback) will be posted soon.
- Our work on bioresorbable battery is published in Advanced Functional Materials, 2025
