Abstract:

 This paper presents a new sensor system for measuring the pedaling strength of human foot and the sustenance between the athlete’s tread and the ground. The system consists of a tri-axial pressure sensor, circuits for data acquisition and signal filtering, and data storage and display modules. The sensor is designed and fabricated with a novel mechanical structure using a new piezoelectric material. Based on the nonlinear model of the dual systems of impact machine, a test-bed to simulate the impact on the foot-ground interface is developed to validate the system. The experimental results well agree with the theoretical curve obtained with the nonlinear model dual systems of impact.

Key words: tri-axial pressure on foot-ground interface, force sensor, the dual systems of impact
