Fields of research

  • Key approaches

 

  • Printing technologies are applied for the manufacture of layers with functionalities beyond color (such as electrical conductivity, porosity…)
  • Digital Manufacturing: One focus is the application of the digital technology inkjet printing which allows a fast change of the pattern for each printout.
  • Conventional Printing: Screen printing is applied when thick layers are required (for printed batteries), gravure printing is optimized for both thin and thick layers.
  • Hybrid Manufacturing: Combination of different technologies in one production line (for example digital and conventional printing technologies, laser patterning)
  • Process Chain: For different applications the complete process chain can be covered (materials development, deposition, drying, and functionalization)

 

  • Printed Electronics

 

  • Batteries
  • RFID / Antennas
  • Conductive Traces for Interconnects
  • Active & Passive Devices for Electronic Circuitry
  • Design Rules for Printed Electronic Circuitry

 

  • Printed Functionalites

 

  • Catalytic Layers (e.g. for fuel cells)
  • Photonic Active Supraballs
  • Microsieves
  • Mechanically Reinforcing Patterns for Thin Fragile Films

 

  • Process Development

 

  • Printing Processes: Digital (Inkjet Printing); Conventional (Screen and Gravure Printing)
  • Functionality Formation in Printed Layers: Intense Pulsed Light Sintering; Thermal Sintering; Drying…
  • Lab-2-Fab: Processes are developed on lab scale and can converted to fab scale
  • Hybrid Manufacturing: Combination of different technologies in one production line

 

 

  • Characterization

 

  • Rheology of inks
  • Morphology and Topography of printed layers
  • Functionality of printed layers (conductivity) and devices (discharge of batteries, performance of electronic circuit devices, …)
