The Power Suit for real:
NEW YORK—Engineers in Japan are perfecting a wearable power suit that amplifies human strength to help lift hospital patients or heavy objects.
Driven by portable batteries, micro air pumps and small body sensors that pick up even the slightest muscle twitch, the Stand-Alone Wearable Power Assist Suit is designed to help nursing home workers lift patients of up to 180 pounds while cutting the amount of strength required in half....
A network of sensors track the wearer's upper arms and legs and waist-muscle activity, then relay the data to an onboard microcomputer that regulates air flow into a series of inflatable cuffs which expand to amplify lifting strength. The suit supports its own weight and carries a battery lifetime of about 30 minutes.
