Meet the iShoe
Erez Lieberman-Aiden had a nagging feeling that his grandmother's death, which occurred after a hard fall, could have been prevented.
But the 30-year-old graduate student at MIT and Harvard did more than fret. He tried to prevent something similar from happening to other older people.
Lieberman-Aiden invented a high-tech shoe insole to help older people manage their balance before a catastrophic fall occurs. His "iShoe" sneaker insoles track a person's balance patterns using digital sensors. The battery-powered footbeds transmit data to computers about a person's walking and standing stability.
