Camera-in-a-pill

A digestible comestible camera inside a pill is being touted in Japan as the new endoscopy alternative:

Computer-simulated footage created for the promotion of the capsule was presented at an international medical symposium in Tokyo recently. In the film, the white capsule illuminated the dark stomach wall and moved along the digestive canal while rotating.

The scenes in the footage resembled those taken by miniature submersible vessels that sometimes appear in science fiction films…

About 40 percent of the capsule's interior is still empty. This space will allow researchers to store medication or surgical tools to achieve a more efficient delivery of drugs or to carry out surgical operations inside the body.
