we present Smart Insole, a physical activity and gait measuring system integrated inside an insole.To achieve its goal, it uses force and acceleration sensors that track the wearer’s movements. The device is fitted with a radio transceiver in order to convey measured information to listening computers. Contrary to previous works which integrate electronic modules into custom shoes, all sensors,control, power and wireless components are integrated on the same insole. Therefore, the user is not restricted to wear a customized pair of shoes. A power saving mechanism has been developed in order to improve the longevity of
the integrated rechargeable battery.
