A group of researchers and engineers working out of MIT, the University of Sheffield and the Tokyo University of Technology have joined forces to develop an exceptionally advanced and high-tech ingestible robot that could be capable of removing harmful foreign objects from your body.
This high-tech robot comprises a special heat-sensitive material that is located between two layers. When heated up, the middle layer contracts, causing the robot to fold according to a split pattern. The robot is compressible enough to be fit inside a capsule that can easily be ingested.
Incredible as it may sound, Americans swallow 3,500 button batteries every year, which is why this ingestible robot could prove to be a life-saving invention.
