Among the nominees is CIPOSA, with Smart Dispensing, a micro-dispensing solution that learns the human gesture in order to automate it with an accuracy of ±5 µm. Thanks to an instrumented cell and modelling of operator know-how, this technology improves the reliability of watch lubrication, technical bonding, micro-assembly and photonics applications, while reducing dependence on experts.
With IotaMetrix, optical metrology reaches a decisive new milestone. A spin-off from the XLIM laboratory (CNRS / University of Limoges), the company offers a patented photon reassignment technology achieving 86 nm lateral resolution, without contact and without sample preparation, even on polished, transparent or reflective surfaces. This is a highly promising advance for high-precision watchmaking, medtech and microtechnology.
Krystalix, for its part, brings forward a major deeptech innovation with its magnetic cold crucible, designed for the growth of ultra-pure single crystals. This patented process makes it possible to exceed 3000°C, drastically reduce contamination and cut energy consumption by 45%, with prospects in luxury watchmaking, defense and microelectronics.
In the watchmaking field, MPS Watch stands out with SpragWay, a miniature one-way bearing capable of transmitting more than 10 mNm with a diameter of 4 mm — that is, 10 times the torque of the OneWay — with an almost zero backlash angle of 0.03°. This innovation is designed for applications close to the barrel and for the most demanding watch complications.
For its part, Louis Bélet SA is pushing back the limits of precision drilling with its PCD drills with internal lubrication. This hybrid architecture, combining a carbide body with a laser-drilled polycrystalline diamond tip, makes it possible to machine ultra-hard or difficult materials. In lead-free brass, a Ø2.28 mm drill has been validated at more than 800 mm/min, without pecking and without tangled chips.
Finally, NanoVoxel is opening up a new path with its VERA™ process, which extends electroforming beyond the limits of traditional LIGA. Thanks to 3D mastering by two-photon polymerization (2PP), the company produces freeform 3D metallic microparts with micron-level precision, submicron resolution and development cycles reduced to around two weeks.
