"high precision capillary printable using 3 carbon-based inks (carbon nanotubes, graphene, nanocellulose) onto both rigid (glass, silicon)/ flexible (paper) substrates... Hummink low energy use printing technique creates features tens of μm long with sub-μm-sized gaps (transistor channel length) for stronger electrical performance... performance comparable to LCD, close to what's needed to drive OLED displays... not intended to replace high-performance silicon chips, can be competitive/ transformative in digital displays"
