Think your webcam is small? Researchers at the Fraunhofer Institute in Germany have developed a camera that's no larger than a grain of salt. The "microcamera" (shown below next to a syringe) has the potential to re-invent medical cameras used to navigate surgeries as well as some aspects of cars and consumer electronics.
"At 1x1x1 millimeters, this camera is as small as coarsely ground grain of salt—the smallest camera that we are aware of," Stephan Voltz, CEO of image-sensor developer Awaiba, said in a Fraunhofer press release.
Part of the challenge for creating effective microcameras is the manufacturing process, which requires that image sensors be created in bulk on a single wafer, then separated and attached to individual lenses. Fraunhofer says it's found a way to mount lenses in bulk on top of the sensor wafer, simplifying—and cheapening—the process, at least for this microcamera.
