Origami Helps Cellphone Cameras To Focus

Sea Monkey writes "New Scientist has an article on the development of novel and ultra-cheap micromotor technology. It's a new type of linear motor, 'using a technique closer to origami than engineering' to cut slits out of tiny piezoelectric ceramic parts. One of the envisioned applications is taking a sheet of the material with the motors, wrapping it into a tube and moving a lens up and down it - instant tiny movable focusing element for cellphone camera lenses."
