Internship : Wireless Implanted Sensor for Animals' Sleep study : energy transfer through skin – duration of 4 to 6 months

Joining Mines Saint-Étienne means committing to an institution where science and innovation build a more sustainable future. It is a school of excellence where everyone has the opportunity to unlock their full potential and contribute to tackling the challenges of tomorrow.

Ranked among the top engineering schools in France and recognized worldwide, our school, a member of the Institut Mines-Télécom, educates the talents of tomorrow while actively addressing major industrial, digital, and environmental challenges. By joining us, you become part of a community of 500 members of staff, 2,500 students and take part in an ambitious project: combining academic excellence, cutting-edge research, and positive societal impact.

The Institut Mines-Télécom brings together France’s leading Grandes Ecoles to tackle 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 engineers and managers. Together, we imagine and build a sustainable future by educating the leaders who will shape tomorrow’s transitions.

🎯 What we expect from you :

As an intern, you will perform innovation and research activities in the field of soft electronics for targeted integration onto animals. Within this centre of Microelectronics and the flexible electronics department, you will combine your passion for science and for societal impact.

The flexible electronics department develops technological and scientific knowledge in the field of soft electronics. The department has a strong knowledge in the field of material and interface electrical and mechanical characterization. The activities of the department are regrouped in the 660m2-area platform. This technological platform regroups facilities and technological equipment for R&D activities in Micropackaging, micro and nano-electronics, in a clean room of 220m² 1000-class and 400m² 10000-class.

The overall objectives of the project are the development of a new implantable, flexible, and wireless electrophysiological sensor, with the following tasks: 1) Fabrication of the implantable sensor (EEG) and electronics; 2) Data and energy transmission through a layer of skin using a radio-frequency (RF) approach; 3) Energy transfer through the skin using an optical approach; 4)Sleep studies on animals

As part of this multi-partner project, the FEL department is leading the fabrication of electronics on ultra-thin (micrometer-range) substrates and the development of energy transmission through the skin (tasks 2 and 4). As an intern, you will work on the development of electronics (light emitter and receptors) in order to transfer energy through the skin.

To achieve this work, it will be necessary to:

· Design or purchase an object than mimic skin optical properties

· Make simple optical simulation for light propagation through skin (with for e.g. COMSOL software)

· Develop an optical approach to transfer energy through the skin in order to power an implanted device.

· Communication and Promotion : Emphasis will be placed on promoting these demonstrators through various means: internal meetings, participation in both internal and external events,

Experimental work in the laboratory is essential and will partly be conducted in our cleanroom.
