'Magic Ink' That Makes Metal Grow, BBC News  Online
 









Excerpts: 
 

Electronic circuitry is usually etched with copper
 


An eco-friendly way of "growing" metal for circuitry or antennas has been
developed by UK firm QinetiQ. 

 The metal printing technique replaces conventional copper etching by using a
special ink which attracts metals.

 It means antennas for tiny mobiles or radio frequency identification (RFID)
tags, used for tracking goods, could be made cheaply and quickly. (...)

Because they connect by radio, they do not require the scanners, so familiar
with the barcoding system, to read their unique identification codes.

 The metal printing technique could transform how RFID tags are made.
