Let’s face it: most cell phone cameras suck. Forcing a camera lens to get small makes it take lower-quality photos. Now, researchers at Rensselaer Polytechnic Institute have developed a liquid camera lens that can take 250 pictures per second. Not only is the lens light and fast, but it also uses less energy than existing technology -– instead of more complex methods, it uses a combination of water and vibration. The lens is made from water droplets that shake back and forth when exposed to high frequency sound and change the focus of the lens. According to the researchers, the lens has applications in a myriad of areas, from cell phone technology to autonomous robots. Say cheese!
