Description du projet :
PVD and plasma spraying technics are nowadays widely used. In the last few decades there has been an intense development in non-equilibrium ('cold') plasma surface processing systems at atmospheric pressure. This new trend is stimulated mainly to decrease equipment costs by avoiding expensive pumping systems of conventional low-pressure plasma devices. Cold plasma become a subject of great interest for a wide variety of technologies including surface treatment and thin-film deposition. However, the current techniques are all based on single nozzle or grouped multi-nozzle solutions, no arrays composed of individually addressable single nozzle are available yet. This interdisciplinary project DigitalPlasma aims through an approach combining current inkjet and single addressing array technology to develop novel and innovative digital cold plasma head.
The consortium will work on:
Single plasma cell, array technology & configuration suitable for digital control
Power electronics and switches
Control and interface system for jet arrays
Plasma on demand with a 2x16 nozzle array as demonstrator
Finally, this will all be built into a digital plasma platform to evaluate the feasibility of digital layer deposition with digital plasma. The project combines the specific & complementary expertise of the 2 involved Institutes: iPrint (HEIA-FR) & Systemtechnik (HESSO-Vs).
