SJTU’s Team Published Paper about Triboelectric Generator Technology on the Applied Physics Reviews

October 03, 2018      Author: Li Rui, Chen Yaqi

In recent days, Professor Li Ye of the School of Naval Architecture, Ocean and Civil Engineering has been invited to publish research on the Applied Physics Reviews (APR). The paper titled "Harvest of ocean energy by triboelectric generator technology"(Appl. Phys. Rev. 2018, 5, 031303, IF = 15.421)describes first systematical clarification for development in harvesting ocean wave energy using difference between triboelectric nanogenerators (TENG) technology and electromagnetic generators (EMG) technology, as well as latest developments In accumulating ocean wave energy.

In this research, Li Ye Research Group was responsible for hydromechanics and study on the physical mechanism of energy conversion while the Group of Professor Zhao Yixin from Shanghai Jiao Tong University School of Environmental Science and Engineering, in charge of materials chemistry research. Two groups worked together to fully compile information and broaden perspectives on harvesting oceanic energy and the use of new materials.

The Applied Physics Reviews, together with the Reviews of Modern Physics, were two prestigious international review journals in the field of physics. Both journals are dedicated to the publication of important experimental and theoretical review articles in scope of physics.


Water wave energy widely distributed in the globe is one of the most promising renewable energy sources. However, it has not been effectively exploited by current energy harvesting technologies which primarily rely on electromagnetic generator (EMG). EMG's have various limitations, especially when operating in environment with irregular and/or low frequencies (<5Hz<5Hz) wave motions. Triboelectric nanogenerators (TENGs) exhibit obvious advantages over EMG in harvesting energy from low-frequency water wave motions. The networking of TENGs has been regarded as a potential method towards large-scale blue energy harvesting. In this review, recent progress of the TENG technology for blue energy harvesting is presented, including a comparison between TENG and EMG in physics and engineering design, and the fundamental mechanism of nanogenerator based on Maxwell's displacement currents is systematically introduced. The review of hydrodynamic TENG, liquid-solid contact electrification TENG, hybrid (dual-modes) TENG, fully enclosed TENG, and TENG network for blue energy harvesting is discussed. The TENG networks are expected to harvest large-scale blue energy from the ocean, which will be a feasible approach for realizing the blue energy dream. Moreover, the energy harvested by TENG from various sources, such as human motion and vibration, is not only new energy, but more importantly, energy using for the new era-the era of internet of things.
