Abstract This study presents a self-powered piezoelectric energy harvesting system integrated into ski (ice) boots, which converts vibrational energy generated between the inner and outer boots during skiing into electrical energy through piezoelectric materials, subsequently powering various functional components. Initially, an analytical investigation was conducted to examine the harvestable energy forms during skiing and the voltage generation characteristics of circular piezoelectric vibrators. A 3D model was subsequently developed for simulation-based experimental validation. A prototype of the self-powered ski (ice) boot piezoelectric energy harvesting system was fabricated and experimentally tested. The experimental results confirm the system's efficacy, demonstrating a maximum output voltage of 204 V under three distinct alternating force application modes. This work provides a technical foundation for mechanical energy recovery in winter sports equipment.
