TRL 6- 7

Generally, opto-chemical sensor systems utilize light and optical properties of indicator materials to detect the interaction between sensor and analyte for determining the analyte`s concentration. Here, only the indicator itself interacts with the analyte. Hence, the remote readout systems are not directly in contact with the sample.

Example 1: New and unique opto-chemical sensors were developed based on the technology of electrospinning. Here, an ultra-fine network of polymer nanofibers is created sensor layers with high surface-to-volume ratio. Hence, the sensors show ultra-fast response characteristics and high sensitivity.

Example 2: Sensor textiles were developed by covalently coupling various indicator dyes to textiles and non-wovens. Upon contact with chemical or biological compounds these textiles change color or fluorescence properties indicating the presence or absence of an analyte. The staining process can be directly integrated into existing textile fabrication processes, thereby opening new applications in the field of clothing, healthcare, ambient assisted living, sports and food packaging.

A wide range of applications for the produced large-area, low-cost, highly resolved, structured foils:

  • Organic Electronics: conductive elements for thin conductors, nanoscale electrodes for organic transistors
  • Light management: optical 2.5D structures on foils for coupling and out-coupling, light guiding
  • Biomimetic structures: 3D-structured surfaces, imitating properties of biological structures
  • Bio-analytics: cost-effective, microfluidic elements on foils for lab-on-foil systems
  • Packaging, decoration, safety, labeling: high-tech film surfaces exhibiting improved optical, mechanical and chemical behavior due to their micro- and nano-structural properties.

RollerNIL

The aim of the rollerNIL project was to use roller-based nanoimprinting techniques to create complex optical structures over a large area in order to particularly replicate biomimetic structural colors. Associated nanoimprint masters and the imprint processes were developed and an inline process measurement system for roller-based fabrication was set up. The imprinting of undercut structures investigated in this project represents a significant development in NIL and shows its large-scale applicability for biomimetic structural colors.

The Department focuses on the development of innovative structuring methods enabling large-area fabrication of flexible micro- and nanostructured foils or fully integrated components. The combination of printing (nanoimprint lithography) and structuring (ultra-short pulse laser techniques, electron beam lithography) methods permits the fabrication of innovative sensor systems. In addition, the group works on the development of circuits built of organic transistors and manufactured by innovative processes on flexible substrates, as there are foil, paper, and textile.
