Pitt, Air Force Researchers Identify Polymers that React and Move to Light

Microvehicles and other devices that can change shape or move with no power source other than a beam of light may be possible through research led by the University of Pittsburgh Swanson School of Engineering. The researchers are investigating polymers that “snap” when triggered by light, thereby converting light energy into mechanical work and potentially eliminating the need for traditional machine components such as switches and power sources.
