IMERSYOM

In recent years, inkjet printing has taken a significant place in the field of low-cost microelectronics, with performances that have become significant. Most of the materials used in the context of this technology remain today in the field of polymers, doped or not, because of the flexibility of their properties (rheological, functional) in view of the characteristics required for printing. In addition, the use of oxides for optics and sensors is now highlighted by virtue of properties exclusive to the semiconductor industry: biocompatibility, abundance of elements and implementation at lower temperatures . The objective of the IMERSYOM project is to make these oxide materials adaptable to inkjet printing technology by working on the formulation of inks composed of microparticles oxides. The printed materials will be functionalized and integrated into a device allowing the optical detection of micropollutants of interest for Geo-Hyd and thus develop a low-cost all-optical metrology. To carry out this project, GREMI has recognized expertise in the production and chemistry of thin oxide films by PVD techniques (laser ablation, magnetron sputtering) and has recently acquired an inkjet printer; GREMAN specializes in the production of oxide materials, in the form of powders and microparticles with adjustable properties, and the ICMN specializes in micro- and nanostructure chemistry, ink formulation and functionalization of materials for sensors.
