Flying Robots Made From Cellophane?

Roland Piquepaille writes "Researchers have discovered that ordinary cellulose is a piezoelectric and smart material that can flap when exposed to an electric field. ScienceNOW reports that electricity can give life to cellophane. When you put a very thin layer of gold on each side of cellophane, and that you apply electric current to the gold layers, one positive, one negative, the cellophane curved toward the positive side. If you switch the voltage fast enough, the cellophane starts to act as a wing. So it should be possible to use it to build lightweight flying robots carrying cameras, microphones or sensors for surveillance missions.

And given that they have a casting cost of 0, we'll have a ton of them.

Need to get my eyes checked.

The first time I read that, I read it as "Flying Robots Made From Cell Phones". That would be seriously scary, getting attacked by a bunch of flying cell phones could ruin your whole day.
