Artificial bug eyes

(American Chemical Society) Single lens eyes, like those in humans and many other animals, can create sharp images, but the compound eyes of insects and crustaceans have an edge when it comes to peripheral vision, light sensitivity and motion detection. That’s why scientists are developing artificial compound eyes to give sight to autonomous vehicles and robots, among other applications. Now, a report in ACS Nano describes the preparation of bioinspired artificial compound eyes using a simple low-cost approach.
