  • spherical triboelectric nanogenerator based on spring assisted swing structure for effective water wave energy harvesting
    Nano Energy, 2021
    Co-Authors: Xi Liang, Tao Jiang, Yawei Feng, Zhirong Liu, Jiajia Han, Pengfei Chen, Zhong Lin Wang
    Abstract:

    Abstract Ocean wave energy is one of the most promising clean and renewable energy sources, so developing effective methods to collect such ‘random’ and ultra-low frequency energy is indispensable. The invention of triboelectric nanogenerators (TENGs) provides new prospects for large-scale blue energy harvesting. In this work, a new spherical TENG based on the coupling of spring-assisted structure and swing structure, integrated with a charge excitation circuit (CEC), was constructed to scavenge water wave energy. The particular structure can transform low-frequency water wave vibrations to high-frequency motions, elevating the frequencies of electrical outputs. Moreover, a TENG array consisting of four TENGs with CECs was fabricated, exhibiting a maximum output power of 16.6 mW and a 205 times enhanced output current of 23.3 mA. The charge excitation TENG array was demonstrated to successfully power a Digital Thermometer and a wireless signal transmission and reception system without any external power supply. Our study not only provides a new type of TENG with improved performance, but also offers a strategy for constructing maritime internet of things (IoTs) system.

  • triboelectric nanogenerator for entire stroke energy harvesting with bidirectional gear transmission
    Nano Energy, 2020
    Co-Authors: Zhong Lin Wang, Guangda Qiao, Qiang Gao, Xiaosong Zhang, Tinghai Cheng
    Abstract:

    Abstract Triboelectric nanogenerators (TENGs) play an important role in harvesting mechanical energy from the environment. Most of their mechanical movements are reciprocating. And the mechanical energy always exists during the entire stroke, which involves the downward and ascending movements. To effectively harvest mechanical energy in the entire stroke, a bidirectional gear transmission triboelectric nanogenerator (BGT-TENG) is developed. The BGT-TENG comprises a platen, a bidirectional gear transmission system, a flywheel and shells. In a series of experiments, optimal setting parameters such as the flywheel mass and the size of the flexible fluorinated ethylene propylene (FEP) film were determined. When the BGT-TENG is acted upon by an external random excitation, reciprocating motion of the platen is transferred to a continuous operation of the flywheel through its bidirectional gear transmission. The BGT-TENG generates electric energy of 2.4 mJ under the low frequency bidirectional equi-spaced excitation of 3.5 Hz. Using a rectifying circuit, the BGT-TENG can power 375 light-emitting diodes, and a Digital Thermometer is powered successfuly. The results imply that the BGT-TENG has a wider application prospect in the field of energy harvesting.

  • spherical triboelectric nanogenerator integrated with power management module for harvesting multidirectional water wave energy
    Energy and Environmental Science, 2020
    Co-Authors: Xi Liang, Chi Zhang, Tao Jiang, Guoxu Liu, Yawei Feng, Zhong Lin Wang
    Abstract:

    With the increasing deterioration of the natural environment, exploiting clean and renewable energy has become the top priority of scientific research today. One of the most prospective routes is to harvest water wave energy using triboelectric nanogenerator (TENG). In this work, a spherical TENG based on spring-assisted multilayered structure was fabricated to collect multidirectional water wave energy, and a power management module (PMM) was integrated to manage the output energy. The output performance of the TENG device was found to be controlled by the water wave frequency, amplitude, and orientation angle between the triggering direction and middle plane. Furthermore, with the PMM, the spherical TENG could output a steady direct current (DC) voltage on a resistance, and the charging speed to a supercapacitor was improved by 100 times. The power-managed performance of the whole TENG was also influenced by the circuit connection configurations among multilayered TENGs. A Digital Thermometer and a water level detection/alarm system were successfully driven by the power-managed TENG as the demonstrated applications. This work not only provides a type of spherical TENG capable of harvesting multidirectional water wave energy, but also effectively manages the output energy for practical applications toward blue energy. Our study demonstrates a typical example of how to build a self-charging power pack that can effectively use random energy in a regulated manner.
