INNOVATION: Memory cells built on paper
.
Via
IEEE.org:
A team based at the National Taiwan University in Taipei has used a
combination of inkjet and screen printing to make small resistive RAM
memory cells on paper. These are the first paper-based, nonvolatile
memory devices, the team says (nonvolatile means that the device saves
its data even when it's powered down).
As Andrew Steckl outlined in his feature for IEEE Spectrum last year,
paper has a lot of potential as a flexible material for printed
electronics. The material is less expensive than other flexible
materials, such as plastic. It boasts natural wicking properties that
can be used to draw fluids into sensors. And it can be easily disposed
of by shredding or burning.
