Flexible inkjet

In the present study, we design a flexible metamaterial absorber on a polymer film, and the conductive patterns are inkjet-printed using silver nanoparticle inks. Compared with previous lithography fabrication processes, the inkjet printing process is very fast, simple, and inexpensive because we can print the pattern from a graphic file using a home printer.

New Approaches for Printed Electronics Manufacturing

In printed electronics, electronic inks are patterned onto flexible substrates using roll-to-roll (R2R) compatible graphic printing methods. For applications where large-area, conformal electronics are necessary, printed electronics holds a competitive advantage over rigid, semiconductor circuitry, which does not scale efficiently to large areas.
