The write-once-read-many (WORM) memories can be fabricated directly on the product or packaging using flexographic or inkjet printing machines, common in the packaging industry.
VTT researchers envisage uses for inexpensive WORM memories in sensor applications, product originality marking, playing cards, interactive packaging and product information cards (e.g. user surveys).
"We expect massive growth from printed electronics, printed memories being a part of this sector. There are many applications for printed memories in Internet of Things and gaming fields to link the virtual and physical worlds. At VTT, we are developing methods that are tested and ready for industrialization," says Raimo Korhonen, Head of Research Area at VTT.
VTT is searching for a partner to commercialise the method patented by VTT.
