MIT researchers have created a vibrating capsule that can send signals to the brain to simulate the sensation of being full, reports Brian Heater for TechCrunch. “The capsule, which is roughly the size of a standard multi-vitamin, contains a vibrating motor, powered by a silver oxide battery,” explains Heater. “After reaching the stomach, gastric acid dissolves the outside layer and completes the circuit, kickstarting the vibration.”
