摘要

将能量收集技术集成到跑鞋中，可以将脚撞击产生的机械能转换为电信号，用于实时监控。这种方法提高了运行效率，降低了受伤风险，并消除了对外部电源的需求。在这项研究中，将无铅压电陶瓷（KNNS-BNZ-xBF）与PDMS结合的复合薄膜用于高效的能量收集和准确的脚击模式检测。XRD分析显示，x >； 0.006为宽R-O-T相共存区（0 ≤x ≤ 0.006），x >； 0.006为向R-T相边界过渡，随着xBF的增加晶粒尺寸减小。样品的xBF = 0.006 mol。%表现出最佳的电性能，并被选择用于复合薄膜的制备。电输出随着陶瓷负载的增加而增加，由于压电响应增强和均匀的颗粒分散，在18 wt% KBB时达到最大开路电压（VOC）和短路电流（ISC）。这些安装在跑鞋鞋底上的薄膜，成功地检测了不同的脚部打击模式（脚后跟，中足和前足）。该系统显示了可穿戴传感器在运动监测和伤害预防方面的巨大潜力。

Piezoelectric composite films for real-time foot strike detection and energy generation

Energy harvesting technology integrated into running shoes enables the conversion of mechanical energy from foot strikes into electrical signals for real-time monitoring. This approach enhances running efficiency, reduces injury risk, and eliminates the need for external power sources. In this study, composite films combining lead-free piezoelectric ceramics (KNNS-BNZ-xBF) with PDMS were developed for efficient energy harvesting and accurate detection of foot-strike patterns. XRD analysis revealed a broad R–O–T phase coexistence zone (0 ≤ x ≤ 0.006) and a transition to an R–T phase boundary for x > 0.006, with reduced grain size as xBF increased. The sample with xBF = 0.006 mol.% showed optimal electrical properties and was selected for composite film fabrication. Electrical output increased with ceramic loading, reaching maximum open-circuit voltage (V_OC) and short-circuit current (I_SC) at 18 wt% KBB due to enhanced piezoelectric response and uniform particle dispersion. The films, mounted on running shoe soles, successfully detected different foot-strike patterns (heel strike, midfoot, and forefoot). This system demonstrates strong potential for wearable sensors in athletic monitoring and injury prevention.
