摘　　要：针对目前可穿戴单兵能源装备对能源采集器件柔性可拉伸能力的迫切需求,提出了一种基于摩擦-压电协同换能机理的一体式柔性可拉伸拱形纳米发电机设计方案。利用混炼工艺将钛酸钡(BaTiO3)、聚四氟乙烯(PTFE)和镀银玻璃微珠分别混入到高温硫化硅橡胶中,分别制备出压电层、摩擦层和电极层,使器件实现了全柔性和可拉伸性能。器件采用拱形结构,可以响应拉伸和拍打两种常见的激励模式,有助于高效采集具有多自由度特点的人体运动能量。实验结果表明,拉伸模式下,器件主要依靠压电层产生电能输出,而在拍打模式下,器件则主要依靠摩擦层产生电能输出,复合输出性能得到明显提升,展现出其在可穿戴单兵能源装备领域广阔的应用前景。Aiming at the growth in demand of flexible stretchable electronic devices for soldier wearable energy equipment,an all-in-one flexible elastic-composite arch piezoelectric and triboelectric coupling nanogenerator(P-TENG)was proposed in this work.Piezoelectric layer,triboelectric layer and electrode layer were prepared by introducing barium titanate(BaTiO3),Teflon(PTFE)and Silver-plated glass beads into high temperature vulcanization(HTV)silicon rubber using mixing technology.Due to the identical matrix employed in the three functional layers,the obtained device can be made into all-in-one structure.Meanwhile,it can respond to the different mechanical stimulations like stretching and flapping modes,facilitating harvest the energy from human body movement.The experimental results show that piezoelectric response dominate under stretching mode and triboelectric response dominate under flapping mode.Meanwhile,the hybrid output performance device can be enhanced remarkable under flapping mode,and 57 LEDs can be lighted by the generated electric energy,which show potential application in the field of soldier wearable energy equipment.
