This study investigates the design and testing of a 3D-printed therapeutic insole embedded with piezoelectric sensors capable of converting biomechanical force from footsteps into electrical energy while providing arch support to alleviate plantar fasciitis. Piezoelectric disks were integrated into a custom-designed insole and connected through a rectifier-capacitor circuit to measure voltage output under applied force. Results showed measurable voltage generation correlated with applied plantar force. Statistical analysis revealed a significant moderate positive relationship between force and voltage (r = 0.596, p < 0.001). The findings support the feasibility of integrating wearable energy harvesting technology into orthopedic footwear for dual-function applications.
This project is very creative and well done! It shows a strong engineering skill, good data collection, and real-world potential. Congratulations on a terrific project.
