According to Med Device Online, “An international team of scientists centered at MIT have further developed a tiny ingestible robot that unfolds from a capsule once swallowed, and could be used to retrieve foreign objects or patch wounds.  New additions to the design include a more biocompatible material and structural modifications that allow the device to be compressed into a swallowable capsule.”  For more information on this new development, please visit: http://www.meddeviceonline.com/doc/ingestible-origami-robot-unfolds-in-stomach-0001
