Special testing device for deviation between actually measured data and theoretical data of insole stress sensor

The invention discloses a special testing device for deviation between actually measured data and theoretical data of an insole stress sensor. The device comprises a sole, an insole arranged on the sole, the stress sensor arranged on the insole, an optical positioning sensor arranged on the sole and a data processing unit electrically connected with the stress sensor and the optical positioning sensor. The data processing unit can judge the motion condition of the foot by detecting the stress data of the stress sensor and the movement data of the optical positioning sensor and send the judged motion condition, the stress data and the movement data of the foot to the host or the control end together for further analysis and use. According to the device, the stress condition of the foot sole and the motion trail of the foot can be detected and reflected, the device is not limited by the using environment, various motion conditions of the foot can be recognized, and therefore real-time stress data of the foot so
