Piezoelectric and triboelectric nanogenerators: Trends and impacts. (October 2018) - Askari, Hassan
Graphical abstract: Highlights: The impact of PENG and TENG to the field of energy harvesting is reported. The trend of publications in the area of NGs is investigated and its correlation with S-shaped history is shown. The trend of citations for PENGs and TENGs is presented. The perspective of the research in this field is discussed. Abstract: Piezoelectric and triboelectric nanogenerators are the two recently developed technologies for effective harvesting of ambient mechanical energy for self-powered systems. The work herein briefly reports the trends and impacts of research based on piezoelectric and triboelectric nanogenerators. For the first time, a statistical study of publication trends in piezo- and triboelectric nanogenerators is used to investigate the current state of the research. We investigate the status of the research in these fields, based on their S-shaped history, as a description of their growth in size over time, considering the number of citations and published papers that use these two novel technologies. A brief discussion of the outlook for these technologies and their potential impact on everyday life is presented, particularly in the development of future 'smart' cities.
