Summary: Traditional approaches for monitoring human gait are not effective in promoting the development of intelligent life involving fitness, sport training, and healthcare due to their spatial and temporal restrictions, complex analysis methods, and high cost. To address this, a portable smart insole system with high spatial resolution and simple manufacturing process is proposed. It can measure plantar pressure distribution anytime, anywhere for gait analysis. The system utilizes an insole-shaped array of 104 piezoresistive sensors that exhibit a good pressure-sensing uniformity. The smart insole not only detects the subtle displacement of the body's center of gravity, but also provides a real-time, high-resolution thermodynamic diagram of the plantar pressure distribution during human activities. Additionally, it can achieve an average recognition accuracy of 83.32% for six predefined motions, making it a promising approach for convenient gait analysis and motion identification in future intelligent life applications.

Summary: Patients with knee osteoarthritis have a unique plantar-pressure pattern during walking, and lateral-wedge insoles may protect against plantar pressure deterioration in these patients. In a study comparing lateral-wedge insoles with ordinary insoles, it was found that the ordinary insole group experienced significant decreases in function and total WOMAC scores, and significant increases in %Trans, %PFP on the forefoot, and %PFP on the heel. In contrast, plantar pressure remained stable in all regions in the lateral-wedge insole group.

Summary: Pressure and shear stresses are critical for diabetic foot ulceration assessment and prevention. However, a wearable system capable of measuring in-shoe multi-directional stresses for out-of-lab analysis is currently lacking. This study reports the development of a sensorised insole system, which showed potential for real-world applications in evaluating foot ulceration risk. The system demonstrated comparable performance to previous research devices and is safe for use by people with diabetes.
