NOVELTY - The utility model belongs to new medical biological monitoring technology field, especially relates to a graphene flexible gait pressure monitoring system based on laser direct writing. comprising an insole, a data collecting module, a data processing module and a wireless communication module; the insole is set on the sole, for monitoring the sole pressure; the data collecting module is connected with the electrode of the graphene pressure sensor through lead; the pressure change obtained by monitoring is converted into electric signal, and amplifying and filtering the electric signal; the data processing module is used for sampling the multi-path analogue electric signal, and converting the analogue electric signal into digital signal, at last, the pressure signal of each region of the sole is packed and sent to the wireless communication module; the wireless communication module uploads the packed data to the upper computer. The insole in the system is completely composed of flexible material, comprising a sensing area, so the softness is greatly improved, which effectively improves the comfort and adhesion, so as to improve the measuring precision.
