Wearable insole-based pressure sensor systems have gained attention for continuous gait monitoring, showing potential preventing, diagnosing, and treating conditions such as lumbar degenerative disease diabetic foot ulcers. However, challenges nonlinear response, low stability, energy limitations hindered widespread adoption. Here, we report a fully integrated, self-powered, wireless smart insole designed plantar monitoring real-time visualization analysis of gait. The uses synergistic strategy, achieving remarkable linearity ( R 2 > 0.999 over 0 to 225 kilopascals) high durability (>180,000 compression cycles). Powered by flexible solar cells, the features 22 sensors, enabling spatially resolved mapping on smartphone interface. Integration support vector machine model further enables accurate recognition eight motion states, including static (e.g., sitting standing) dynamic walking, running, squatting) activities. provides practical solution improving clinical assessments, personalized treatments, biomechanics research.

This study presents an IoT-based gait analysis system employing insole pressure sensors to assess kinetics. The integrates piezoresistive within a left foot insole, with data acquisition managed using ESP32 board that communicates via Wi-Fi through MQTT IoT framework. In this initial protocol study, we conducted comparative the Zeno system, supported by PKMAS as gold standard, explore correlation and agreement of obtained from system. Four volunteers (two males two females, aged 24–28, without disorders) participated walking along 10 m path, equipped sensors, while wearing Vertical ground reaction force (vGRF) were collected over four cycles. preliminary results indicated strong positive (r = 0.87) between reference measurements. A Bland–Altman further demonstrated mean difference approximately (0.011) systems, suggesting minimal yet significant bias. These findings suggest may offer promising cost-effective solution for disorder assessment monitoring. However, operational factors such high temperatures sensor placement footwear can introduce noise or unwanted signal activation. communication framework proved functional reliable during protocol, plans future expansion multi-device applications. It is important note additional validation studies larger sample sizes are required confirm system’s reliability robustness clinical research

Abstract Gait analysis is an important indicator for evaluating athletes' technical level and physical condition, but traditional methods have limitations on the accuracy real-time performance of gait. Therefore, this article proposes a novel gait method using optical holographic imaging technology pressure sensor technology. This establishes experimental system consisting device sensor, which captures data athletes converts it into digital signals. By technology, obtain 3D images athletes, as well detailed information such joint angles motion trajectories. Pressure sensors can measure distribution feet in real-time, providing more comprehensive data. Subsequently, collected analyzed identified, accurate patterns are established through training models classifying different types. The research results indicate that based great potential be applied to improvement sports.
