Abstract

For harvesting, mechanical energy converts to electrical energy using piezoelectric devices. In this study, piezoelectric flexible (PF) was synthesized form composite materials of polyvinylidene difluoride adding 1 wt.% of carbon nanotube (PVDF-1wt.%CNT). The PVDF-1wt.%CNT size 0.5 × 30 × 100 mm³ and annealed at 60 °C for 1 h. A copper tape was compressed for electrode on the top and bottom of the PF, poling at 6 kV mm⁻¹ for 20 min. The results show that the piezoelectric coefficient (d₃₃) maximum was 7 pC N⁻¹. The 5 PF modules was fabricated to a device and attachment on a motorcycle coil spring compressor to investigate the generating electricity of the PF from mechanical energy. The motorcycle was tested using velocity at 50 km h⁻¹ for 5 min run-on various surface road. The electricity from the PF modules were arranged using rectifier circuit installed motorcycle coil spring compressor, the output voltage was 3, 3.3, and 4 V for asphalt, cement, and gravel road, respectively. It expected that the energy harvesting devices using piezoelectric flexible is useful to apply on a motorcycle for generated electricity.

摘要

对于收获，机械能使用压电设备转换为电能。在这项研究中，压电柔性（PF）是由聚偏二氟乙烯的复合材料合成而成的，其中添加了1 wt。％的碳纳米管（PVDF-1 wt。％CNT）。PVDF-1wt。％CNT尺寸0.5×30×100 mm ³并在60°C退火1 h。在PF的顶部和底部压制一条铜带作为电极，以6 kV mm ^-1极化20分钟。结果表明，压电系数（d ₃₃）最大值为7 pC N ^-1。将5个PF模块装配到一个设备上，并安装在摩托车螺旋弹簧压缩机上，以研究通过机械能发电PF的过程。在50 km h ^-1的速度下，在各种路面上行驶5分钟，对摩托车进行了测试。PF模块的电力是使用安装在摩托车螺旋弹簧压缩机上的整流电路布置的，沥青，水泥和碎石路的输出电压分别为3 V，3.3 V和4V。期望使用压电挠性的能量收集装置可用于在摩托车上发电。
