The concepts of printed electronics offer a tremendous potential when brought to nanotechnology. Weprovidean all-in-one solution to print a wide range of nanomaterials, including metallic nanoparticles, nanowires, and semiconductor quantum dots. Printed lines are thinner than a single micrometre, with a width to height aspect ratio close to 1. The printing process does not require clean-room conditions and can be performed on different substrates, e.g., glass, flexible foil, and printed circuit boards. We developa complete solution to print a wide range of nanomaterials. This includes proprietary technology, oursubmicron lab printer, and the formulation of inks. The technology is protected by patents. In our mechatronics laboratory, we design and manufacture the printer and the formulation of inks is tailored with respect to a specific application in our chemical laboratory. Our approach is based on a guided assembly of nanoparticles. During the printing process, nanoparticles chaotically distributed in a liquid solution (ink) are guided by the external electric field and form a conductive line. The heart of ourprinter is the printing head, which allows a precise application of ink. The process is controlled by an unique algorithm, which adjusts the printing parameters based on the feedback from the measurement system. It is possible to print a wide range of nanomaterials (metallic nanoparticles and semiconductor quantum dots). ourinks are tuned by changing their physicochemical properties, as well as the shape and distribution of nanoparticles. The printing process can be performed on different substrates.
Our technology allows to print a wide range of nanomaterials on different substrates. The width of printed lines ranges from 100 nm to 1 μm, andthe width-to-high aspect ratio is close to 1. Compact design of oursubmicron lab printer: ink dispensing, line formation, and drying process are combined in a single printing head. 3-axis precise positioning system with an accuracy below a single micrometre. Our ink is optimized with respect to its physicochemical properties, as well as the shape and distribution of nanoparticles.
Any application requiring thin transparent conductive films (TCF), including solar cells, displays, touch screens, and flexible electronics. Functionalized nanostructures for biosensors. Reparation of electrical defects in integrated circuits, e.g., TFT arrays and printed circuit boards. Anti-counterfeiting. Any other applications in printed electronics where ultra-thin conductive lines can be an advantage.
Low-cost submicron printing method on different substrates. The printing process does not require clean-room conditions. Width to height aspect ratio close to 1 is obtained in a single run of the printing head. Extremely low amount of ink can be dispensed, so that the ink consumption is minimal. The printing process is controlled by an intuitive and easy to learn user interface.
