    Établissement recruteur:
The Flexible Electronics Department (FEL) in Gardanne is part of the Provence Microelectronics Centre
(CMP), one of the five research centers of Mines Saint-Etienne, itself a School of the Institut Mines
Telecom. Its skills include flexible and stretchable electronics, heterogeneous integration, energy
harvesting and flexible batteries. The department's research is motivated by developing autonomous
and communicating electronic systems for the design of sensitive interfaces, electronic skin, medical
devices, etc.


Description:


Significant progress in the field of optical telecommunications and astronomy were achieved these last decades thanks to the control of optical aberrations using active shape mirror technology.

Yet,
commercial mirror technologies are still suffering from fragility, temporal bandwidth, dynamical range, and size limitations and their cost.

As part of the FlexSiMirror (PEPR Origins) project, we aim to develop a new lightweightmirror technology based on self-supportingsilicon membrane driven by, 3D-printed electroactive polymer actuators.

The polymer is sandwiched between two conductive electrodes electrically polarized in order to induce mechanical displacement.

  • In this context, conductive electrodes for electroactive polymers (EAPs) need to have specific mechanical and electrical characteristics in order to withstand the mechanical stresses induced by the actuation mechanism and minimize charge injection phenomena induced by alternating polarization.
  • To achieve these objectives, we propose to evaluate both commercial inks and inks developed inhouse.
  • In this context, the internship will involve:
  • benchmark compatible commercially available conductive inks through a literature review
- synthesize and formulate new conductive inks adapted to our needs.
- print these inks (direct to write) using the N scrypt machine available in our laboratory
- carry out electrical characterizations:
frequency conductivity, work function ; mechanical

characterizations:
stretchability (Young's modulus) and bending; as well as morphological
- characterizations (SEM, FTIR, AFM, etc.).


Profil:

The master fellow should have a background in nano-materials science or chemistry, and have
autonomy and good communication skills
