Randy Atkins: Surfaces as small as your I-pod screen or as large as your wall may soon be engineered to detect subtleties of touch in multiple locations at once.  Ilya Rosenberg, a New York University researcher, says applications could range from medical sensors to musical instruments.

Ilya Rosenberg: Really rich things that are found in the physical world that up until now have not been possible to do with electronics because there wasn’t a low-cost sensor.

Randy Atkins: Rosenberg is sandwiching a force sensitive ink between two layers of paper-thin plastic with printed-on electrodes.

Ilya Rosenberg: When you squish down onto the surface, it squeezes those two layers together which produces a measureable change.

Randy Atkins: All the nuances in a drawing, for example, could be recorded electronically.

Ilya Rosenberg: You can lay like 10-20 sheets of paper on our device and write on it, and we can actually sense the force of the pen right through the paper.
