Purdue researchers have created a magnetic "ferropaper" that might be used to make low-cost "micromotors" for surgical instruments, tiny tweezers to study cells and miniature speakers. Babak Ziaie, a professor of electrical and computer engineering and biomedical engineering, holds a miniature birdlike shape made from the material. The wings move slowly, but the structure is not capable of flight.
