Origami MEMS motors to improve mobile phone cameras

According to New Scientist, UK company 1 Limited is developing tiny motors made from piezoelectric ceramic materials that could provide zoom and focus features to inexpensive mobile phone cameras. A .1 mm sheet of piezoelectric ceramic is cut and molded so hundreds of tiny bridges on legs protrude from the surface. The sheet is then rolled into a cylinder around a lens. Applying current causes the legs to flex, moving the lens up and down inside the cylinder. Link Discuss
