Functional inks for applications in printed electronics and sensor technology using microprinting processes such as inkjet, aerosol, screen and dispenser printing

Our working group researches and develops functional inks and pastes for applications in printed electronics and sensor technology as well as for their integration in flexible and portable applications. The areas of application are diverse. They range from the production of components for gas sensors with miniaturised heaters and highly sensitive measuring electrodes for biomedical sensors to catalytically improved infiltrations or printing of electrodes for fuel cells and printed silicon layers for photovoltaics and lithium-ion batteries.

We utilise modern methods and equipment such as nanotechnology, microprinting processes, molecular plasma treatment and laser sintering. The range of substrate materials that can be used is very broad and includes paper, polymer films, textiles, metals, ceramics and glass.

The direct printing approach offers decisive advantages:

• Cost and time savings: The printing processes used, such as inkjet, aerosol jet, screen printing and dispensers, avoid complex thin-film processes and reduce material consumption.
• Flexibility and fast prototyping: Prototypes of printed electrodes can be produced quickly and improved iteratively using printing processes.
• Customisability through digital printing: Inkjet in particular enables easy adaptation of the print geometries using software in order to meet the requirements of different applications (e.g. sensor layouts).
• Scalability: The technological approach offers high scalability so that large quantities of printed parts can be produced cost-effectively and in a short time (roll-to-roll production).

Material spectrum

The functional inks and pastes are specially adapted to the respective printing process. They are based either on nanoparticles, which are produced in-house, or on commercial powders. IKTS also develops customised printing formulations on customer request or in joint research projects. The range of materials is broad and includes:

• Nano inks made of Au and Pt for electrodes and sensor layers. The gold and platinum inks have been successfully tested several times in the form of printed electrodes for biocompatibility in accordance with DIN EN ISO 10993-5 / -12
  Innovative solutions for printed electronics and biocompatible electrodes
• Metal inks such as Ag, Cu, Ni and Si are suitable as materials for electrical cables or energy storage devices.
• Carbon inks such as graphite, graphene and CNTs can be used as more cost-effective and alternative electrode materials.
• Magnetic inks such as Fe-Ni are suitable for printed magnetic sensors.
• Marking inks based on ceramic colour bodies and glass with a temperature stability of 500 °C to 1300 °C are used for permanent marking and digital traceability of metallic or ceramic components using printed data matrix codes when other marking solutions such as laser marking or engraving are not an option.
• Resistance and composite inks (e.g. Ag glass, RuO₂ glass)
• Special inks on customer request

Example of nano inks for microprinting processes

Electronically conductive nano inks are examples of our ink formulations for inkjet and aerosol printing processes. They are based on self-synthesised nanoparticles that are stably dispersed in the solvent. These inks have been developed for the digital and high-resolution printing of electronically conductive tracks or electrodes for a wide variety of substrate materials. The formulations are compatible with polymer or paper substrates through to ceramic and glass substrates. Our silver ink, for example, is electrically conductive at temperatures as low as 100 °C. Our inks are used in product development for biomedical sensors, printed circuit carriers and various functional elements in printed electronics and sensor technology.

Printing equipment

We utilise various printing technologies for joint research projects:

• Inkjet printing
  o   Dimatix DMP SAMBA (up tp 21x32 cm² print size),
  o   Pixdro LP50 (up to 23x33 cm² print size) and
  o   Ceradrop F-Series (up to 31x31 cm² print size) with Fujifilm and Konica Minolta printheads
• Aerosol-printer M3D from Optomec Inc. (up to 20x20 cm² print size)
• Screen printers from EKRA semi and fully automatic E5, X5, HX2 (up to 25x25 cm² print size)

Functionalisation technologies

In addition to the formulation of inks and pastes, IKTS has modern systems for substrate pre-treatment based on molecular plasma. This can further improve the wetting and adhesion of the print layers on a wide variety of substrate surfaces. After printing, the layers undergo thermal treatment, which is the only way to realise the function of the printed layer (e.g. electrically conductive, semi-conductive or formation of catalytic nanophases). A variety of sintering furnaces are available for this purpose, as well as fast photonic sintering processes such as lasers or flash lamps. This means that printed layers can also be processed on thermally sensitive substrates.

• Molecular plasma system for pre-treatment of the substrate surface of MPG (up to 21x30 cm² surface size)
• Continuous line laser treatment (HDPL, 30 mm scan width)
• Flash lamp process from Novacentrix (FLA)
• UV and IR curing

Our answer to the technical challenges of printed layers

Thanks to our extensive experience in the research and development of functional materials in combination with various printing technologies and heat treatment processes, we are able to address common technological problems in printed electronics and sensor technology:

• Coating thickness range from 0.1 to 100 µm
• Adhesion even on challenging substrate surfaces thanks to ink chemistry and substrate pre-treatment
• Adjustment of electrical conductivities and target resistances
• Print quality (e.g. fine line printing, miniaturisation)
• Aspect ratio of the print layer
• Scaling the technology for commercial applications
• Customisation of printing materials
• Extensive scientific equipment in the field of chemical, thermal, mechanical and microstructure characterisation

We organise consortia and participate as project partners in national and European research projects. We also carry out feasibility studies for customers. Thanks to our network, we can bring together partners from research and industry.
