A new lab is working to perfect special shoe insoles that can help monitor access to high-security areas, such as nuclear power plant or military bases, by using sensors within the insoles to check the pressure of feet, monitor gait and use and microcomputer to compare the patterns to a master file for that person to verify his or her identity, according to an article from The Associated Press.
This is a biometric shoe – a concept based on research that shows each person has unique feet and ways of walking. If the patterns match the bio-soles’ master file, the sensors go to sleep. If they don’t, a wireless alarm message can be sent out, the article says.
