The researcher will be part of the MEMS Bioinspired team of IEMN Laboratory. This team has been working for several years on the manufacturing of flying objects that mimic insects [1-3], in close collaboration with the ENSAM-LISPEN Laboratory, which has a solid expertise in design and vibration calculation of nonlinear electromechanical systems [4-6].
He/she will work under the supervision of Professor Sébastien Grondel, Professor Eric Cattan, Assistant Professor Sofiane Ghenna from IEMN and Professor Olivier Thomas from LISPEN within the framework of the ANR Astrid NANOFLY project (https://anr.fr/Projet-ANR-19-ASTR-0023) whose aim is to demonstrate the hovering ability of a nano aerial vibrating wings vehicle to operate with an electromagnetic actuator.

The researcher will be in charge of the three tasks described hereafter :
-Task1: The first axis will deal with the design, the modelling and simulation of the nano aerial vehicle structure and the electromagnetic actuator. The goal is to get closer to the performance of flying insects capable of generating large amplitudes and lifting their weight several times. Therefore, the Post-Doc candidate will have to consider all solutions possible for the reproduction of a kinematics and lift similar to that of insects.
-Task2: The second axis will focus on the manufacturing and testing of nano aerial vehicles prototypes. In particular, the researcher will work on the development of an instrumentation and measurement bench for the control of the nano aerial vehicle hovering as well as on the programming of the closed loop control.
-Task3: The researcher will be responsible of the administrative and scientific aspects of two workpackages in the NANOFLY project: the first one being the design, simulation and manufacturing of nano aerial vehicles (Task 1), the second one being its hovering ability demonstration (Task 2). He will also have to ensure a good coordination with the other partners of the project, in particular those who work on the prototypes aero-elastic performances and will assist the team's professors in supervising master and doctoral students.
The researcher must hold a PhD.
Experience in multiphysics or aeroelastic modeling and simulation is mandatory.
Skills in the following research areas would be an advantage:
In addition, experience and a great interest in micro- and nanoaerial vehicles would be a plus.
The IEMN-CNRS is spread over sites of Valenciennes and Villeneuve d'Ascq in France, whereas ENSAM-LISPEN is located in Lille.
The researcher will work in a state of the art cleanroom environment and will have full access to the micro & nanofabrication platform of the IEMN laboratory (https://www.iemn.fr/plates-formes/cmnf/equipements).
She/He will work in close collaboration with experts from nanotechnology and nano aerial vehicles.
