- Abstract:
- A rapid low-pressure plasma sintering process of inkjet-printed silver nanoparticles is reported,
yielding a conductivity of 11.4% of bulk silver within 1 min of plasma exposure and a final
conductivity up to 40% of bulk silver for longer sintering times. The maximum processing temperature
did not exceed 70 °C, which enabled the use of cost-effective polyethylene terephthalate (PET) foils.
Fully functional radio-frequency identification (RFID) tags were prepared with inkjet-printed antennas,
which showed similar results as screen-printed devices. The inkjet-printed antennas require significantly
less materials, hence thinner layers, than the screen-printed references.
