Abstract Traditional approaches for monitoring human gait have severe spatial and temporal restrictions with complex analysis methods high cost, which are powerless to promote the development of intelligent life involving fitness, sport training, healthcare. Herein, a portable smart insole system resolution simple manufacturing process measure plantar pressure distribution anytime, anywhere is proposed. An insole‐shaped array 104 piezoresistive sensors highly robust characteristics assembled, exhibiting good pressure‐sensing uniformity. The not only detects subtle displacement center gravity body, but also exhibits real‐time, high‐resolution thermodynamic diagram during activities. More importantly, function motion intelligence identification can be realized by regionalizing digitizing whole distribution, achieving an average recognition accuracy 83.32% among six predefined motions. These results imply that carbon fiber‐based provide effective approach convenient identification, has great potential in application future life.
