Internship Offer – Design and Fabrication of a Flexible Electronic Circuit for a Portable Gas Sensor – 5 to 6 Months

English version

Joining Mines Saint-Étienne means committing to an institution where science and innovation are building a more sustainable future. It is a school of excellence where everyone has the opportunity to reach their full potential and contribute to meeting tomorrow's challenges.

Ranked among the best engineering schools in France and recognized internationally, our school, a member of the Institut Mines-Télécom, trains tomorrow's talents while actively engaging with major industrial, digital, and environmental challenges. By joining us, you will be part of a community of 500 staff members and 2,500 students, and participate in an ambitious project: combining academic excellence, cutting-edge research, and positive societal impact.

The Institut Mines-Télécom brings together the largest French Schools to address major industrial, digital, energy, and environmental challenges. With its eight public Grandes Écoles and two affiliated Graduate Schools, it is the leading public institute dedicated to the training of engineers and managers. Together, we imagine and build a sustainable future by training the leaders who will shape the transitions of tomorrow.

The flexible electronics department develops technological and scientific knowledge in the field of flexible electronics. The department has solid expertise in the electrical and mechanical characterization of materials and interfaces. Its activities are grouped within a 660 m² platform. This technological platform brings together facilities and technological equipment dedicated to R&D activities in micropackaging, micro- and nano-electronics, within a 220 m² cleanroom of class 1000 and 400 m² of class 10,000.

🎯 What we expect from you

As an intern, the candidate will carry out innovations and research activities in the field of electronics. Within the flexible electronics (FEL) department of the Provence Microelectronics Center (CMP), the candidate will combine a passion for science with a desire for societal impact.

This internship is part of the Sens-CO research project, which partners the Gustave Eiffel University, the École Polytechnique, and the École des Mines de Saint-Étienne. This project aims to develop a portable NOx and COx gas sensor for continuous environmental monitoring. The internal resistance of the sensor varies with the concentration of the measured gas. The CMP's role is to accurately obtain the value of this resistance through an electronic circuit and to enable correlation with gas concentration, as well as data processing and transmission via contactless communication. This circuit must allow for portable measurement and therefore needs to be realized on a flexible substrate.

The candidate will thus have to, starting from a design made on a rigid PCB, transpose this gas sensor interface onto a flexible substrate, taking into account the challenges related to these methods. Given the high value of the resistances to be measured, the final PCB must allow for:

· A precise measurement of large resistance values

· Low noise and resistance to electromagnetic interference, taking into account the arrangement of components to ensure maximum flexibility.

🔍 What we are looking for:

You are currently in your final year of an engineering school specializing in electrical engineering, electronics, embedded systems, or related fields.

You must:

· Demonstrate a strong interest in electronics, embedded systems, and fabrication (soldering, routing, and realization of electronic circuits).

· Have experience with electrical circuit design tools, as well as PCB design and electromagnetic compatibility.

An experimental approach and knowledge of printed circuit board design are essential.

🌍 Why join Mines Saint-Étienne?
