Cabot Superior MicroPowders (CSMP), is developping printable electronics, such as antennas and transistors, made of conductive inks and polymers, rather than etched or subtracted, from pure-metal materials.

In the coming years, printed antennas will likely replace the solid-copper antennas used in RFID tags, lowering their costs down from 20 to 60 cents each to 15 to 30 cents each. In the longer term, printable electronics could allow for the full RFID transponder�antenna and processor�to be printed, and even produced straight into packaging or products.
