Low-cost disposable endoscopic camera that is the size of a coarse grain of salt.
Tiny video cameras mounted on the end of long thin fiber optic cables, commonly known as endoscopes, have proven invaluable to doctors and researchers wishing to peer inside the human body. Endoscopes can be rather pricey, however, and like anything else that gets put inside peoples’ bodies, need to be sanitized after each use. A newly-developed type of endoscope is claimed to address those drawbacks by being so inexpensive to produce that it can be thrown away after each use. Not only that, but it also features what is likely the world’s smallest complete video camera, which is just one cubic millimeter in size.
