  • stacked pendulum structured triboelectric nanogenerators for effectively harvesting low frequency water wave energy
    Nano Energy, 2019
    Co-Authors: Wei Zhong, Liang Xu, Zhong Lin Wang, Haiming Wang, Ding Li
    Abstract:

    Abstract The invention of triboelectric nanogenerators (TENGs) provides an effective approach for harvesting water wave energy that is clean and renewable. Here, stacked pendulum-structured triboelectric nanogenerators for harvesting low-frequency water wave energy is proposed. The device works based on a pendulum-like principle through a compact disk-track structure that enables area contact instead of point contact while maintaining the susceptible rolling motion. Thus the tribo-electrification and the Output are greatly enhanced in slow water waves. While only considering the volume of the TENG units, Charge Output density of 4622 μC m−3 can be achieved, which is more than 13.2 times of a typical ball-shell structured device. A peak power density of 14.71 W m−3 and an average power density of 1.05 W m−3 are obtained in low-frequency water waves below 0.5 Hz. The device shows great potential of the rolling area-contact design to enhance the Output of TENG-based wave energy harvester with excellent low-frequency performance, which is crucial to the development of TENGs for effectively exploiting abundant water wave energy.

  • coupled triboelectric nanogenerator networks for efficient water wave energy harvesting
    ACS Nano, 2018
    Co-Authors: Liang Xu, Tao Jiang, Jia Jia Shao, Chuan He, Wei Zhong, Xiangyu Chen, Zhong Lin Wang
    Abstract:

    Water wave energy is a promising clean energy source, which is abundant but hard to scavenge economically. Triboelectric nanogenerator (TENG) networks provide an effective approach toward massive harvesting of water wave energy in oceans. In this work, a coupling design in TENG networks for such purposes is reported. The Charge Output of the rationally linked units is over 10 times of that without linkage. TENG networks of three different connecting methods are fabricated and show better performance for the ones with flexible connections. The network is based on an optimized ball-shell structured TENG unit with high responsivity to small agitations. The dynamic behavior of single and multiple TENG units is also investigated comprehensively to fully understand their performance in water. The study shows that a rational design on the linkage among the units could be an effective strategy for TENG clusters to operate collaboratively for reaching a higher performance.

  • magnetoelectric resonance behavior of simple bilayered pb zr ti o3 tb dy fe2 epoxy composites
    Journal of Applied Physics, 2007
    Co-Authors: Zhan Shi, Yuanhua Lin, Cewen Nan
    Abstract:

    Magnetoelectric resonance behavior of a simple, bilayered structure of Pb(Zr,Ti)O3 ceramic chip and (Tb,Dy)Fe2∕epoxy mixture layer is investigated. Our results show that there occur three kinds of resonance, which are attributed to the first-order flexural, second-order flexural, and radial resonance modes, respectively. The measured phase spectra show a significant phase change around each resonance frequency. The thinner PZT chip is benefit for higher flexural resonance magnetoelectric effect. The magnetoelectric effects measured under open and short electric boundary conditions show different behaviors. This simple bilayered structure exhibits a large Charge Output of about 300pC∕Oe at the resonance frequency.
