Elaboration of 3D electronic and RF circuits through digital printing technology for “communication systems”

Printed electronic: rheology of complex fluids, surfaces and interfaces physico-chemistry, deposit processes, electromagnetic properties, plastic materials forming processes

Communication systems: electromagnetic modeling, multi-physic modeling for circuits for HF and RF communications, sensors, antenna, 3D RF components.

CONTEXT
This thesis work is a part of the industrial Chair MINT funded for five years by the Foundation Grenoble INP. The project partners are two laboratories of University Grenoble Alpes, as well as the international Schneider Electric society, specialist of energy management.
This ambitious project aims to explore the new technologies sustainable and low cost of printing and of functional inks for the design of wireless communication functions in 3-dimensions inside plastic housings (electrical boxes, switches…).
After a preliminary study realized by a Post-Doctorant on conventional deposition processes – such as Screen Printing – and their adaptation to direct printing onto thermoplastic substrates used by Schneider Electric, the candidate will investigate the development of digital processes through a similar methodology:

– Characterization and adaptation of processes to 2D and 3D substrates
– Adaptation of 3D direct printing tools
– Conception of electronic circuits for IoT and RF for 2D and 3D shape factors
– Characterization of realized systems for a long term and robust performance

The expected work is multidisciplinary, involving knowledge in material rheology, surfaces and interfaces physico-chemistry on one hand, and RF and electronic circuitry design and modeling on the other hand. These competences will be devoted to the development, through digital printing processes, of new generation of 3D electronic circuits and wireless communication systems, from their design to their characterization.

PROFILE OF THE APPLICANT
Preferentially with a training in applied physics, the applicant will have to deal with aspects concerning both materials (rheology, physico-chemistry, …), communication systems, but also electromagnetics and multi-physic modeling. He will have to show a great curiosity and be able to build a large basis of knowledge, with the help of the whole skills constituted by Schneider Electric and the two world-renowned laboratories of Grenoble.
Due to the ambitious proposed subject, the PhD student will present his results in the major international conferences and will publish in the major journals of the explored domains.
