摘要

本文首次实现了液晶增强驻极体振动能量采集器。研究了杂质和湿度对向列相液晶(LC)电阻率的影响。通过抑制操作环境中的离子杂质和湿度吸收，可以获得$10^{16}\Omega \ mathm {c}\ mathm {m}$的极高电阻率。通过在驻极体/电极之间引入LC，获得了比气隙高7倍的输出功率，持续时间超过40小时。此外，利用傅里叶变换红外(FT-IR)光谱分析了LC在电极间隙附近的对准。在此基础上建立了发电模型，仿真结果与实验数据吻合较好。

Effect of Impurity/Humidity on Liquid-Crystal-Enhanced Electret Vibration Energy Harvester

In this report, the liquid-crystal-enhanced electret vibration energy harvester has been realized for the first time. The effect of impurities and humidity on resistivity of nematic liquid crystal (LC) was examined. By suppressing the ionic impurities and humidity absorption in the operation environment, extremely-high resistivity of $10^{16}\Omega \mathrm{c}\mathrm{m}$ can be obtained. By introducing LC between the electrets/electrodes, 7-times higher output power compared to the air gap has been obtained for over 40 hours. Furthermore, the LC alignment near the electrode gap is also investigated with Fourier-transform infrared (FT-IR) spectrometry. The power generation model is proposed based on the present finding, and the simulation results agree well with the experimental data.
