A tiny camera that fits inside a pill-sized capsule has revolutionised cancer screening in Scotland. Over two thousand patients have now used the PillCam rather than the more traditional invasive method of having a colonoscopy. The PillCam has reduced waiting times for bowel cancer screening and allowed faster diagnoses, an important factor in battling the disease.
We’ve seen some pretty tiny spy cameras so far, and scientists keep pushing the limits. Researchers from the University of Washington have developed a camera that’s so tiny, that it looks like a backpack for beetles. If you’ve ever wanted to see the world from a bug’s perspective, now you can.
At just 200 microns in diameter, this may very well be the smallest camera in the world. Patrick Gill, a senior research scientist for a technology licensing company named Rambus, has developed a camera sensor that can capture pictures while still retaining a near-microscopic size.
