摘要
Energy harvesting technology has received significant attention around the globe over decades. However, it meets with difficulties of achieving high output performance under non-resonant frequency. In this paper, a non-resonant rotational triboelectric energy harvester with high output performance, which relied on the coupling of triboelectrification and electrostatic induction, was presented. The harvester introduced a cylindrical stator and disk-shaped rotor, which are made of NdFeB. Without complicated movement mechanism, the stator and rotor, of a higher pair have theoretical line contact by magnetic attractive force. Under a hand shake frequency of about 8Hz, the peak-peak value can reach to 140V. The maximum power of 0.31mW was obtained at a resistance of about 10(7)Omega. In addition, the voltage can reach up to 154V when running at a speed of 8 km/h on the treadmill. The harvester can be potentially used as a power supply to intelligent wearable devices.
