IEMN-CNRS is looking for a design/research engineer in micro-fabrication of components on flexible substrates.

Development of a 3D measurement sensor specifically for healthy feet.
Optimization of stimulation electrodes for the cochlea.

The position is to be filled on February 01, 2024 for a period of 16 months.
The research work will be carried out on the IEMN Villeneuve d'Ascq site, with some travel to IEMN Valenciennes. The candidate will work in a state-of-the-art cleanroom environment and will have full access to the laboratory's micro & nanofabrication platform (https://www.iemn.fr/plates-formes/cmnf/equipements).
He/she will work in the Bioinspired MEMS team in close collaboration with experts in micro-technologies.

The candidate will be involved in the Piéouté and Robocop projects. The Piéouté project aims to develop an instrumented 'sock' to characterize the movement and position of the foot in a shoe during walking/running up/downhill. The originality of this interdisciplinary project lies both in the use of microtechnologies to manufacture the distributed sensor device integrated into a thin, flexible structure, and in obtaining information on whether or not the foot makes contact and/or slips in the shoe, by combining on-board electronics. The Robocop project aims to make a cochlear implant active by associating actuators with it. The stimulation electrode is revisited: it is manufactured in a thin layer (polyimide) coupled with 20 gold electrodes.

Proximity detected as the finger approaches the sensor. Cochlea stimulation electrode and insertion test. 

The candidate will be responsible for building and optimizing prototypes for the Piéouté project, combining approach measurement with sliding measurement (a 3-axis pixel). Simulation work will be required to optimize electrode overlap and hence the sensitivity of capacitive sensors. The candidate will also work on the manufacture and optimization of the stimulation electrode coupled with polymer actuators for the Robocop project. The candidate will carry out insertion tests on 3D-printed medium and large cochleas. The candidate will liaise with project partners LAMIH, LPPI, Inria Lille, Institut Pasteur.

The Bioinspired MEMS team is internationally recognized in the above fields, and its work is state-of-the-art.

The candidate should have experience in micro/nano manufacturing in a cleanroom environment, if possible in the field of flexible electronics. Modeling and dimensioning skills are desirable.
