Engineering team develops self-powered mobile polymers

One of the impediments to developing miniaturized, "squishy" robots is the need for an internal power source that overcomes the power-to-weight ratio for efficient movement. An international group involving Inha University, University of Pittsburgh and the Air Force Research Laboratory has built upon their previous research and identified new materials that directly convert ultraviolet light into motion without the need for electronics or other traditional methods. The research, "Photomotility of Polymers," was published today in the journal Nature Communications.
