Offre de Post-Doctorat pour le développement d’antennes et métamatériaux textiles pour la récupération de l’énergie électromagnétique ambiante

Contexte

Ces dernières années, les objets connectés se sont immiscés dans la vie quotidienne, et des textiles connectés commencent à être proposés sur le marché. D’autres produits, dits textiles intelligents, comportant des capteurs et modules d’électroniques embarquées se sont aussi développés en s’orientant vers le marché professionnel (vêtements militaires ou de sécurité) et vers les domaines de la santé et du sport.
Cependant, leur fiabilité reste discutable en particulier à cause de problèmes liés à la connectivité et à l’alimentation des modules électroniques. Parmi différentes solutions d’alimentation, la récupération de l’énergie électromagnétique ambiante (ondes Wifi, GSM, TNT) est envisagée. Pour récupérer cette énergie, il est nécessaire de développer des antennes rectifiées (rectennas) composées dans le principe d’une antenne et d’un circuit de redressement. Cependant, une variante à l’antenne peut être l’utilisation de la localisation des champs observée dans les structures métamatériaux, et le circuit de redressement peut être réalisé au moyen d’une électronique dédiée.

Le projet LUMINOPTEX  (http:/project.web4projects.com/project/Luminoptex/Partenariat) est un projet Interreg France-Wallonie-Vlaanderen qui porte sur la conception et la mise en œuvre de nouveaux textiles intelligents pour des applications d’éclairage ambiant autonome dans les contextes du design intérieur, des tissus décoratifs ou de la signalétique.
Le projet fédère les compétences de six partenaires : le centre de R&D Materia Nova de Mons (Chef de file), le centre de R&D CENTEXBEL de Gand, le laboratoire GEMTEX de l’école d’ingénieur ENSAIT de Roubaix, l’IEMN (Institut d’Electronique de Microélectronique et de Nanotechnologie) de Villeneuve d’Ascq, l’ICTEAM de l’Université Catholique de Louvain, et le CIRMAP de l’Université de MONS. Dans le cadre de ce projet, les travaux menés par l’IEMN et l’ENSAIT portent plus particulièrement sur le développement de textiles permettant la récupération de l’énergie électromagnétique ambiante.

Description du poste

Dans le cadre du projet LUMINOPTEX, la personne recrutée aura pour mission le design et la caractérisation électromagnétique d’antennes et de structures métamatériaux textiles permettant de capturer le plus efficacement possible l’énergie des ondes WiFi et GSM. Pour cette application, les métamatériaux textiles pourront être considérés comme solution pour réduire la taille des antennes ou comme motifs résonnants propres permettant la localisation du champ électromagnétique en vue d’une amélioration de la conversion AC/DC.

Dans un premier temps, il sera demandé de définir et d’optimiser des antennes et des métamatériaux réalisables en technologie textile (broderie, tricot, tissage) par l’intermédiaire de simulations sur des logiciels commerciaux (HFSS, CST). Les structures seront alors proposées au partenaire ENSAIT et discutées avec lui. L’ENSAIT prendra alors à sa charge la fabrication de prototypes, et des simulations supplémentaires pourront être nécessaires suivant les contraintes de fabrications rencontrées. La seconde partie des missions portera sur la caractérisation électromagnétique des structures fabriquées à l’ENSAIT (pertes de retour, adaptation d’impédance, directivité, diagramme de rayonnement). Ces caractérisations seront menées au sein des plateformes de caractérisations RF et CEM de l’IEMN. Enfin, l’étude du circuit de rectification ne fait pas partie des missions principales de la personne recrutée. Cependant, elle pourra être sollicitée ponctuellement pour contribuer aux caractérisations électromagnétiques de composants et circuits électroniques dédiés, développés parallèlement dans le cadre du projet LUMINOPTEX.

Profil du candidat

Vous êtes docteur en électronique ou en physique appliquée spécialiste des hyperfréquences.
Vous avez une expérience notable en caractérisations électromagnétiques et vous maîtrisez les logiciels de simulations HFSS et/ou CST. Vous avez des connaissances approfondies en hyperfréquences, et des connaissances en métamatériaux seraient appréciées.
Idéalement, vous avez déjà développé des antennes rectifiés.

Postdoc – Development of micro-transfer technologies for zero-newton placement and bonding of ultimately thin semiconductor chips

Background: Foldable, thin, light-weight, stackable, high performance – that’s the promise that flexible electronics and integration of highly heterogeneous functional and structural materials holds today. Smart systems featuring ubiquitous intelligence such as wireless sensor networks, micro-aerial vehicles, embedded defense, security and biomedicine chips, environment monitoring and smart textiles are all applications that flexible electronics and heterogeneous integration would make take off. To realize that objectives, microsystems (comprising digital, embedded memories and analogue signal processing), RF circuitry, antennas, sensors, actuators and microfluidics need to be developed. In that context, IEMN develops a flagship research project on flexible electronics featuring the two distinctive trademarks: i) high performance multi-Ghz flexible electronics ii) heterogeneous integration of smart materials and functional blocks onto mechanically flexible/stretchable substrates. In support to this scientific/technological program, the LEAF Equipex platform provides innovative laser-based micro-patterning techniques.

Description of work: The overall objective is to develop alternative placement and bonding technologies of thinned high frequency chip (100 µm² large and 10 µm thick) on flexible substrates. In particular the work aims at designing zero-newton placement and bonding strategies of thin semiconductor chips onto plastic foils. To do so the candidate will have to integrate state of the art knowledge on (i) surface energy modification by geometric and chemical modification and on (ii) interplay between capillary and elastic forces between flexible thin film and liquid droplets. The work will be performed in the clean-rooms of IEMN where state of the art equipments are available (see website) to study and optimize wafer grinding and surface texturing processing steps and to set-up and to characterize microfluidic experiments [1-4]. Special emphasis will be put on polymer coating of hydrophobic substrate, on conformal flattening of semiconductor micro-sheets onto plastic foils and on the use of surface tension and elasticity gradients for chip self-placement.

Duration: 18 months appointment available immediately – start date before 1st January 2014

Salary: ~2350-2500€ gross/month, ~1950-2050€ net/month according to profile

Location: Institut d’Electronique, de Microélectronique et de Nanotechnologie – IEMN, Villeneuve d’Ascq (F)

Requested qualification: Ph.D. in micro-nanotechnologies with strong experience in polymer science, microfluidics and clean-room processing. Proficiency in flexible electronics is an advantage.

Object: 18 months Position of Postdoc

Key words: Technology Process, MEMS/NEMS, EM and Mechanical simulations (COMSOL)

Context:

In the framework of a new large project (EQUIPEX ExCELSiOR-NCC), IEMN will create a new characterization platform for nanosciences gathering a large set of new experimental instruments operating at the interface between nano-microscopy and high frequency measurement tools. One of them, not commercially available, will be built from a high resolution MEB set-up equipped with AFM head and two nano-manipulators. This new instrument will be dedicated both for the study of structural behaviours and high frequency electrical mechanisms of nanodevices such as semiconducting nanowires, carbon nanotubes as well as other 1D and 2D materials with high dynamic properties.

 

For the high frequency aspect, a new class of micrometer/nanometer size high frequency probes, not exiting today, have to be designed and fabricated. These probes will be realized using the technological facilities of IEMN (www.iemn.univ-lille1.fr) within the expertise of research group in the fields of MEMS fabrication and high frequency design. The recruited research engineer will have in responsibility the fabrication of these probes and the optimization of the process flow.
