Abstract A plantar force measurement system was designed based on the pressure sensor. Selecting the layout of the pressure sensor, designing the signal conditioning circuit to amplify and filter the collected pressure signal, the hardware platform was build and the signal acquisition interface was designed; The sensor calibration experiment and the foot force measurement system experiment were performed to collect the pressure signal when the object was walking at different speed at different statement; Taking the proportional calculation, determining fuzzy sets, designing membership functions, the fuzzy processing was carried out and the fuzzy rules was established by Larsen product Hint method, finally, the gait phase was inferred from the fuzzy output signal.

Key words： metrology plantar force measurement system pressure sensor gait recognition fuzzy theory
