Dude

Designed at the Kanagawa Institute of Technology (KAIT) in Atsugi, Japan, the suit resembles a flak jacket or the lead vest that people wear when getting dental X-rays. A bladder in the belly fills up with water, simulating the growth and average weight of Japanese babies. Similar bladders in the chest expand to simulate breasts filling with milk. A series of actuators that lie against the wearer’s stomach fire on and off to give the sensation of a kicking baby, and sensors on the tummy allow the wearer to relieve the kicking by rubbing the belly.
