Jin received the Endeavour Fellowship from the Department of Industry, Innovation, Science, Research and Tertiary Education (DIISRTE) of the Australian government in 2012 and Victoria Fellowship from the Department of Victorian State Development Business and Innovation in 2013. ![]() Before joining UNSW, she worked at the Institute for Frontier Materials, Deakin University as a postdoctoral research fellow, the Sir Lawrence Wackett Aerospace Research Centre, RMIT University as a research fellow, and the Australian Future Fibres Research & Innovation Centre as a senior research fellow. Jin Zhang received her PhD from Deakin University and is currently a Scientia Senior Lecturer at the University of New South Wales, Sydney, Australia. Future applications and commercialization opportunities of these nanogenerators are also reviewed. The main strategies for improving electrical output performance are identified and examined, including novel nanostructures for increasing the contact area of the triboelectric pair, and nano-additives for enhancing the surface potential difference between the triboelectric pair and piezoelectric layers. Herein, we review the recent advances of hybrid piezo–triboelectric nanogenerators, with a particular focus on microstructure design, synergy mechanisms, and future research opportunities with significant potential for physiological monitoring, health care applications, transportation, and energy harvesting. Due to their large surface-area-to-volume ratios and outstanding mechanical, electronic and thermal properties, nanomaterials are favourable building blocks for constructing hybrid nanogenerators and represent a large family of flexible energy harvesting electronic structures and devices. The unique, synergistic electrical coupling mechanisms of piezoelectric and triboelectric effects increase the electric outputs and energy conversion efficiency of hybrid generators to beyond a linear summation of the contributions from individual triboelectric and piezoelectric mechanisms. Hybrid piezo–triboelectric nanogenerators constitute a new class of self-powered systems that exploit the synergy of piezoelectric and triboelectric mechanisms to improve energy harvesting efficencies and address the energy and power needs of portable and wearable electronic devices.
