Printing Copper RFID Tags | Antenna Application

We set out to create an UHF (ultra-high frequency) RFID tag using an innovative nano copper ink by Copprint. In this video, we printed an RFID tag on NOVA, our materials dispensing system, with Copprint's LF-301 copper ink. There are many benefits to printing additively with copper ink: 📈Increased performance over off-the-shelf RFID tags 🖨️Material is only deposited where it is needed, eliminating copper waste and toxic byproducts ♻️The final RFID tag is recyclable (if printed on paper) Once printed, we followed the sintering instructions provided by Copprint; sintering is a critical step for nano copper inks as it transforms the structure of the material, from many disconnected microscopic particles of copper to one continuous bulk. With the antenna printed and processed, all that was left was to bond the RFID transceiver integrated circuit (IC) to the antenna itself. This IC controls the antenna and responds to an incoming RFID signal. Want to learn more about the process? Check out our white paper: https://www.voltera.io/use-cases/whit...
