中文摘要:
      针对现有智能纺织品电源不能实时充电、携带不便等实际问题,为了更好地实现智能纺织品自供电以及电源能量的收集与存储,利用压电式人体俘能技术,课题组搭建了一种输出功率较高、能量损耗小、制造成本低的压电式人体腿部俘能装置,并对影响该压电俘能器电学输出性能的因素进行了测试与分析。研究发现:在穿戴试验测试中,压电俘能器选取0.1 mm厚的弧形基板、反弧度的弯曲方式,步行和跑步的开路输出峰峰值电压分别为18.8 V和22.2 V;当外部负载为100 kΩ时,压电俘能器出现最大瞬时输出功率为2.016 4 mW;在能量收集过程中,经1 200 s后,电解电容存储的能量为3.730 9×10-3 J,可以成功点亮LED灯。
英文摘要:
      In order to solve the practical problems of the existing smart textiles power supply, such as real time charging, carrying inconvenience, etc. and to realize self supply of power, energy collection and storage of the smart textiles, a piezoelectric energy capture device for human legs with high output power, low energy loss and low manufacturing cost had been assembled based on piezoelectric energy capture technology. The factors which affect the electrical output performances of the piezoelectric energy capture device were tested and analyzed. Research results reveal that the peak voltages of the open circuit output peak for walking and running are 18.8 V and 22.2 V respectively by selecting a 0.1 mm thickness curved substrate and a reverse arc bending mode for piezoelectric energy capture device. When the external load is set to be 100 kΩ, the maximum instantaneous output power of the piezoelectric trap is 2.016 4 mW. After the energy collection process of 1 200 s, the energy stored by the electrolytic capacitor is 3.730 9×10-3 J, which light the LED lamp successfully.
