Tiny ribbons that generate electricity when flexed and flex when stimulated with electricity have been developed to flap the wings of mechanical dragonfly spy drones, but the technology can also find uses ranging from powering iPods and cell phones to charging batteries by converting to electricity the vibration of devices deployed in data centers. (...)
Researchers at Princeton University have embedded these brittle ribbons in silicone rubber, allowing them to flex and also protect them from environments where they might be deployed, such as in shoes - to capture mechanical energy as people walk in them - or implanted within humans - to capture the motion of lungs to power pacemakers.
