If engineers at the University of California have their way, "Power Dressing" could be back in vogue. However, instead of 80’s-style shoulder pads the engineers have been creating energy-scavenging nanofibers. These nano-sized generators could one day be woven into clothing and textiles to harness the energy created through normal body movements to power mobile electronic devices.
