I had to read this paragraph from an Economist article about 3D printing twice:
Xerox’s PARC research centre in Palo Alto, California, is developing ways to use such inks. These can print circuits for various components, including flexible display screens, sensors and antennae for radio-frequency security tags. With the emergence of additive-manufacturing techniques, it starts to become possible to print such things directly onto the product itself, says Janos Veres, the manager of PARC’s printed-electronics team.
Sounds like Xerox’s PARC is pioneering the future once again.
Pay attention to 3D printing. This is going to be a very big deal.
