RTO Competences

Market of application

The most important market sectors are:

  • Automotive / transportation
  • Energy
  • Environment
  • Food
  • ICT industry (including electronics, computer and communication related products)
  • Medical & Healthcare
  • Production technology (machinery / equipment / automation)

Three detailed examples:

Applications for 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.

Applications for large-scale, low-cost printed sensors (PyzoFlex®), which can be integrated into any curved or textured surface:

  • Consumer Electronics: Human-Machine-Interfaces, wearables, sport
  • Security: job safety, 360° motion detection, biometrics, access control
  • Smart city & smart living: user-oriented, efficient technologies  for smart buildings/offices
  • Ambient & Assisted Living: fall detection
  • Collaborative Robotics: artificial skin
  • Life sciences: large-scale, medical diagnostics
  • Automotive industries: energy harvesting, security
  • Vibration Monitoring : for structural health, condition monitoring and Industry 4.0
  • Energy harvesting applications for low power devices

Applications for laser- and plasma-assisted coating methods:

  • Medicine: Optimization of polyurethane human implant surfaces (artificial heart) by biocompatible coatings to prevent thrombosis formation.
  • Industry: Coating of plastic gears with diamond like carbon (DLC) to improve wear resistance and reduce friction.
  • Plant engineering: Using plasma-assisted chemical vapor deposition (PACVD) in order to deposit thin layers directly from the plasma. A mechanism for coating the inner surface of tubing makes it possible to apply layers of polymer to inner surfaces of hoses and pipes. In a combined plasma system, planar substrates and three-dimensional components can be treated on the surface by: plasma etching, activation, coating and fluoridation.
  • Coating materials: The functional coatings, which are only a few nanometers to a few micrometers thick and can be applied to metals, ceramics, plastics and composites, are desirable for their biocompatible, antibacterial, anti-adhesive (non-stick), adhesive, sensory, catalytic, tribological, wear-resistant, decorative, optical, electronic, electrical, anti-corrosive, gas-permeable or impermeable, or dielectric characteristics according to the different applications in which they are used.
