The EndoPil weight-loss capsule can be triggered magnetically to create a feeling of fullness.
Developed by researchers from Nanyang Technological University, the prototype EndoPil is equipped with a balloon that will be automatically released when the capsule reaches the stomach. Once in place, the capsule is triggered via a handheld magnet to allow separately stored acid and salt to mix, creating carbon dioxide to inflate the balloon. The space taken up by the inflated balloon causes a feeling of fullness, helping to control the urge to eat. The balloon can also be deflated magnetically for removal, though the team is working on an automatic deflation system as well as making the capsule a bit easier to swallow.
