Capillary Printing of Advanced Transistors and Watch Parts

Abstract :

While various printing technologies exist, each has its advantages and limitations. High Precision Capillary Printing (HPCaP) addresses these challenges. It utilizes capillary forces for ink deposition, achieving high resolutions at the micron and sub-micron scale with exceptional precision.
Fully printed transistors have gained increasing attention for the past years because of their cost efficiency, design versatility, and enhanced performances. As a technology capable of depositing a wide range of active material, such as conductors or polymers, HPCaP has been used in collaboration with renown labs to demonstrate its ability to print fully functional transistors. Thanks to the reduced gap between the printed electrodes, superior electrical measurements have been achieved.
Luxury watchmaking predominantly revolves around the production of high-quality, upscale products. The dials of these watches, which are often the centerpieces of their design, are meticulously crafted using expensive, delicate, and fragile materials. HPCaP delivers high-resolution decorations with a continuous adaptation to substrate topography. Notably, HPCaP's capabilities extend beyond mere decoration, and it can dispense a variety of inks, from precious metals and quantum dots for lighting, to functional materials like resins and glues. Given these attributes, HPCaP is being closely examined as a viable technology for both functionalizing and personalizing watches.
