Ink has been used for millennia to convey ideas, but it may be about to convey something new: electricity.
Don't worry. This isn't about getting a shock off a printed page. Rather, it's about making electronics cheaper ? at a fraction of a cent ? by replacing wires, circuit boards and batteries with ink.
A small, New York-based outfit called T-Ink Inc. is pioneering the use of electrically conductive ink in ordinary printing presses
"Our goal is a total print medium where your paper is going to talk," says Andrew Ferber, vice chairman at T-Ink and one of the brains behind the technology. He envisions newspapers that include printed loudspeakers, batteries and circuits.
