TRL 4-5

Inkjet printingand aerosol jet printingare digital, contactless methods for a patterned material transfer onto a substrate. Both methods allow rapidly changing patterns and avoid substrate contamination.  They enable the direct deposition of electronic, optical or biological structures on various substrates, such as metallic conductors, semiconductors, resistors, ceramics, composite materials, dielectrics or biological materials.

In inkjet printing, small droplets are generated by a nozzle, providing good control over lateral structure size and deposited liquid volume.

In aerosol jet printing, functional inks are atomized. The aerosol is continuously fed via a tubing system to the print head, which focuses and directs the aerosol jet onto the substrate. The nozzle is about 1-5mm above the surface permitting the use of non-planar substrates. This high level of resolution method allows the deposition of solutions and dispersions with a wide range (1-2500 cps) achieving a minimum structure width of 10 µm. Depending on the process duration and the used materials, it is possible to generate different layer thicknesses or to build multilayer structures by overprinting.

H2020 Project: Hi-Response 646296

The HI-RESPONSE project is based on the development of a highly innovative Pulsed Electro-Static Printing Technology. Among the various printing technologies Pulsed Electro-Static Printing represents a novel deposition technique capable of applying functional inks in a viscosity range, droplet volume and at a frequency currently not available for classical piezo based ink jet technologies, but bearing the fundamental capability to fulfil market requirements in various fields. Thereby Pulsed Electro-Static Printing technology is able to bridge the gap between high and low ink viscosities within on deposition system. The enhanced viscosity range of inks is able to prevent fundamental issues or significantly reduces effects like coagulation of particles as known for nano-particle inks for inkjet printing and Pulsed Electro-Static Printing enables the exploitation of functional inks to novel fields of applications.

H2020 Project: INSPIRED 646155

The INSPIRED project aims at overcoming limitations of the printed electronics industry by ensuring that suitable functional nanomaterial formulations (inks) are available for end users in industrial scale quantities. The main goal is the production of these nanomaterial formulations on an industrial scale and subsequently depositing them using cost-effective, high throughput printing technologies in order to enable rapid production of printed electronic devices on a wide variety of substrates.

Our researchers specialize in the development and technological implementation of chemical and biological sensors. These are compact analytical systems that allow for continuous monitoring of chemical, metabolic or biological parameters such as, for example, oxygen, glucose or lactate, but also of toxic gases, heavy metals, bacteria and toxins.

The research team is a leader in the development of optical chemical sensors (optodes) and measurement systems used in process control, medical diagnostics, environmental analysis, authentication and food monitoring.

In addition, new materials for screen printing, inkjet printing and aerosol-jet printing of electrode structures, as well as methods for surface functionalization and structuring of polymeric materials for biosensors, are developed.
