A new lab is working to perfect special shoe insoles that can help monitor access to high-security areas, like nuclear power plants or special military bases. The concept is based on research that shows each person has unique feet, and ways of walking. Sensors in the bio-soles check the pressure of feet, monitor gait, and use a microcomputer to compare the patterns to a master file for that person. If the patterns match the bio-soles go to sleep. If they don’t, a wireless alarm message can go out.
