The concept for these insoles builds on extensive research that shows each individual has unique feet and ways of walking. The biometric soles include several sensors designed to check the pressure of feet, monitor gait (i.e. the way of walking), and use a microcomputer to compare the patterns with those registered in a master file for that person. If the patterns match, no harm done. If not, a wireless alarm message can be triggered. “It’s part of a shoe that you don’t have to think about,” said Marios Savvides, head of the new Pedo-Biometrics Lab at Carnegie Mellon University in Pittsburgh, according to the Associated Press (AP).
