Sound Wave-Driven Liquid Lenses Good For Lightweight Future Phones, UAVs

Scientists at Rensselaer Polytechnic Institute have come up with this freaky adaptive liquid-lens that can capture 250 in-focus images per second. It's essentially droplets of water in a pair, trapped in chamber and driven by a high-frequency sound wave to oscillate.As the drops wiggle back and forth, surface tension… » 9/23/08 6:12am 9/23/08 6:12am
