摘　　要：摩擦纳米发电机(TENG)在收集低频振动能量方面具有显著优势,但也存在输出电能不稳定和能量利用率低等问题。针对这些问题,设计了一种摩擦电式低频振动能量收集装置以及电源管理电路。该振动能量收集装置设计了固定于外壳的振动轴,使振动块在振动时有轨迹地上下运动,同时搭配了弹簧,使振动效果更加显著,并增加了缓冲效果。通过所设计的电源管理电路,充电效率明显提升,特别是在电容为3.3μF时,充电效率相比于直接充电电路提升了2.5倍。此外所设计的电路还体现出较强的带负载能力,满足了为温湿度传感器连续供电的需求。该装置在低频振动能量收集领域和TENG的电源管理电路设计方面具有巨大的潜力,拓展了TENG的实际应用范围。The triboelectric nanogenerator(TENG)has significant advantages in harvesting lowfrequency vibration energy,but there are also problems such as unstable output power and low energy utilization.Aiming at these problems,a triboelectric low-frequency vibration energy harvesting device and a power management circuit were designed.The vibration energy harvesting device is designed with a vibration shaft fixed to the shell,which can make the vibration block move up and down with a track during the vibration.At the same time,it is equipped with a spring,which makes the vibration effect of the vibration block more significant and increases the buffering effect.Through the designed power management circuit,the charging efficiency has been significantly improved.Especially when the capacitance is 3.3μF,the charging efficiency is 2.5 times higher than that of the direct charging circuit.In addition,the designed circuit also shows a strong load capacity to meet the needs of continuous power supply of the temperature and humidity sensor.The device has great potential in the field of low-frequency vibration energy harvesting and TENG power management circuit design,which expands the practical application range of TENG.
