Listen to The Discovery Files radio feature – SALT GRAIN SIZE CAMERA!
Imagine one day being able to use the entire back side of your cell phone as a camera! Researchers at have developed a camera the size of a grain of salt that, despite being just a half millimeter wide, it can take clear, full-color images as crisp as cameras 500,000 times its size. Such a micro-sized camera could lead to extraordinary advances in medical diagnosis and care, and significant improvements in robotic sensors. Learn more at NSF's "The Discovery Files."
