Erez Lieberman, a Harvard-MIT graduate student, has devised the iShoe that will help physicians detect balance problems before falls occur. Given a $50,000.00 grant from the Lunar Ventures Competition to take it past the prototype stage, Lieberman originally developed the shoe for NASA to help them monitor balance problems incurred by astronauts after they return from space. While there he managed to come up with a new system for collecting data and an algorithm to analyze it.

Because his own grandmother had a bad fall a while back, Lieberman realized that the tech could help others. The iSole may also be equipped with an alarm that would let other family members know that a fall has occurred.
