摘要
As a promising renewable energy source,it is a challenging task to obtain blue energy,which is irregular and has an ultralow frequency,due to the limitation of technology.Herein,a nonresonant hybridized electromagnetic-triboelectric nanogenerator was presented to efficiently obtain the ultralow frequency energy.The instrument adopted the flexible pendulum structure with a precise design and combined the working principle of electromagnetism and triboelectricity to realize the all-directional vibration energy acquisition successfully.The results confirmed that the triboelectric nanogenerator(TENG)had the potential to deliver the maximum power point of about 470μW while the electromagnetic nanogenerator(EMG)can provide 523 mW at most.The conversion efficiency of energy of the system reached 48.48%,which exhibited a remarkable improvement by about 2.96 times,due to the elastic buffering effect of the TENG with the double helix structure.Furthermore,its ability to collect low frequency wave energy was successfully proven by a buoy in Jialing River.This woke provides an effective candidate to harvest irregular and ultralow frequency blue energy on a large scale.
