Schellack für gedruckte Schaltungen

Umweltfreundliche Elektronik

(PresseBox) (Dübendorf, )
Intelligente Verpackungen mit Sensoren, die etwa Nahrungsmittel wie Gemüse auf langen Transportwegen überwachen, sind ein Zukunftstrend. Doch solche «Einweg-Elektronik», die in Massen gedruckt wird, macht auch Probleme: Metalle in Drucktinten sind teuer – und ihre umweltgerechte Entsorgung ist aufwändig und verschärft das Problem des Elektroschrotts. Eine neue Lösung von Empa-Forschern soll hier Abhilfe schaffen.

Präziser, schneller, günstiger: Forschende in aller Welt arbeiten seit Jahren daran, elektrische Schaltungen mit additiven Verfahren wie Roboter-3-Druck («Robocasting») herzustellen – mit grossem Erfolg, der mittlerweile allerdings zum Problem wird. Die Metallpartikel, die solche «Tinten» elektrisch leitfähig machen, verschärfen das Problem des Elektroschrotts.
