Abstract
Triboelectric Nanogenerators (TENGs) are a part of paradigm shift that is on horizon in the field of cardiac energy harvesting for powering pacemakers. However, such designs require highly invasive thoracotomies resulting in low chances of technology advancing to human clinical trials. In this work, an innovative Multiwalled Carbon Nanotubes (MWCNT) – Polydimethylsiloxane (PDMS) based Single Electrode (SE) TENG is developed and integrated to the pacemaker leads for effectively harnessing energy from the movements of the pacemaker lead due to cardiac motion. Finite element simulations are conducted on the pacemaker lead for comprehensive understanding of its deformation behaviour and fluid dynamic characteristics. An inventive approach is employed to non-invasively investigate the dynamics of pacemaker lead in different patients. Experimentally, a novel Pacemaker Lead Motion Simulator (PLMS) system is developed for performing rigorous in-vitro tests of SE-TENG integrated pacemaker lead. The maximum peak-to-peak open circuit voltage of SE-TENG corresponding to complex motion of pacemaker lead (12 mm - 60°) is 1.44 V aligning with the pacemaker lead motions in patient 1. The PLMS system is further modified to analyse the performance of SE-TENG in liquid environment generating output of 0.4 V at 25 mm Hg pressure. Furthermore, power management system is designed to directly power a commercial pacemaker. This innovation eliminates the reliance on batteries showcasing its potential to enhance comfort, minimise invasiveness and improve long-term health outcomes while setting new standards particularly for paediatric patients thereby making a global impact with sustainable cardiac care.
摩擦电纳米发电机(TENGs)是为心脏起搏器提供能量的心脏能量收集领域即将发生的范式转变的一部分。然而,这种设计需要高度侵入性的开胸手术,导致技术发展到人体临床试验的机会很低。在这项工作中,开发了一种创新的基于多壁碳纳米管(MWCNT) -聚二甲基硅氧烷(PDMS)的单电极(SE) TENG,并将其集成到起搏器导联中,以有效地利用由心脏运动引起的起搏器导联运动产生的能量。为了全面了解起搏器导线的变形特性和流体动力学特性,对其进行了有限元仿真。采用一种创造性的方法来无创地研究不同患者起搏器导联的动态。实验上,我们开发了一种新型的起搏器导线运动模拟器(PLMS)系统,用于对SE-TENG集成起搏器导线进行严格的体外测试。与患者1起搏器导联复杂运动(12 mm - 60°)对应的SE-TENG最大峰间开路电压为1.44 V,与患者1的起搏器导联运动一致。进一步改进了PLMS系统,分析了SE-TENG在液体环境下的性能,在25 mm Hg压力下产生0.4 V的输出。此外,电源管理系统旨在直接为商用起搏器供电。这项创新消除了对电池的依赖,展示了其提高舒适度、减少侵入性和改善长期健康结果的潜力,同时为儿科患者设定了新的标准,从而对可持续的心脏护理产生了全球影响。
