Monitoring foot conditions is essential, as existing screening methods often need more objectivity and cost-effectiveness. This research develops an insole-based screening device using self-powered triboelectric nanogenerators (TENGs) as tactile sensors and Arduino hardware setup. TENG converts mechanical energy into electrical energy, offering simple fabrication, cost-effectiveness, longevity, and high-output power benefits. The device records the electrical output generated by foot movements via Arduino and sends data via Bluetooth to the processing tool. Machine learning algorithms employing the Random Forest Classifier process the data to detect flatfoot conditions accurately after training sessions. For data collection, 100 participants are asked to march and walk for the same duration and distance, ensuring consistent output. Analysis reveals that the insoles' middle sensors produce higher electricity levels in individuals with flatfoot, showing a uniform pressure distribution across the foot and contact in the arch area. In contrast, individuals with normal feet exert more pressure on the toe and heel foot areas. The system achieves an overall accuracy of 82\%, demonstrating the insole's potential as a commercial flatfoot detection device.}, year = {2025} }

Through introducing innovative solutions for energy harvesting and autonomous sensing, this research presents a cost-effective strategy to enhance the performance of triboelectric nanogenerators (TENGs). The TENG was fabricated from polyvinylidene fluoride (PVDF) and N, N′-poly(methyl methacrylate) (PMMA) blend with a porous structure via a novel optimized quenching method. The developed approach results in a high β-phase content (85.7\%) PVDF/3wt.\%PMMA porous blend, known for its superior piezoelectric properties. PVDF/3wt.\%PMMA modified porous TENG demonstrates remarkable electrical output, with a dielectric constant of 40 and an open-circuit voltage of approximately 600 V. The porous matrix notably increases durability, enduring over 36 000 operational cycles without performance degradation. Moreover, practical applications were explored in this research, including powering LEDs and pacemakers with a maximum power output of 750 mW m−2. Also, TENG served as a self-powered tactile sensor for robotic applications in various temperature conditions. The work highlights the potential of the PVDF/PMMA porous blend to utilize the next-generation self-powered sensors and power small electronic devices.}, year = {2025} }
