Situation
This approach makes it possible to structure multilayer stacks with nanometric precision in thickness in order to create coloured, decorative, or functional surfaces. Initially developed as part of a feasibility study between BFH-ALPS and Plasmadiam, the technology opens up new opportunities for the watchmaking industry, particularly for producing pigment-free, high-resolution multicolour watch dials. It also has potential applications in optics, microfluidics, anti-counterfeiting, and nanostructured surfaces. The project brings together complementary Swiss and French partners: BFH, Gravity Swiss, Plasmadiam, UTBM, SAIREM, and SILSEF. Together, they cover the entire value chain, from thin-film design and optical modelling to laser ablation, tool manufacturing, nanostructure replication, and process industrialization.
Course of action
The main objectives are to develop coloured thin-film coatings and establish a database of laser ablation thresholds for these thin films, enabling the fabrication of multicolour watch dial prototypes and nanostructured moulds, as well as the preparation of an industrial equipment concept. Through this project, BFH contributes to strengthening cross-border innovation in ultra-precision technologies and to transferring an invention from applied research towards high-potential industrial applications. The implementation of the project was made possible thanks to the Interreg France-Switzerland programme, which funds the project through the European Regional Development Fund (ERDF), the Swiss Confederation, and the cantons of Bern and Neuchâtel.
