A critical review of the recent progress on Carbon Nanotubes-based Nanogenerators

Research output: Contribution to journalReview articleContributedpeer-review



The paper presents a substantial review of the research done on the use of carbon nanotubes to fabricate and utilize nanogenerators. Carbon nanotubes have been one of the leading nanomaterials that have been employed to fabricate dynamic sensing prototypes. The exceptional electromechanical characteristics of carbon nanotubes have led scientists to use them in different physiomechanical forms. The use of carbon nanotubes to form the electrodes of the sensors increases the overall efficiency in terms of sensitivity, robustness and longevity. Among the sensing applications, nanogenerators are devices that have constantly been growing popular due to the continuous shortage of available energy resources in the current world. The focus has been drawn on the fabrication of nanogenerators by combining a range of materials to generate high-quality prototypes. The use of carbon nanotubes to form nanogenerators has been highlighted, where different kinds of pure and composite devices have been developed using carbon nanotubes and utilized for energy-harvesting applications. The paper also highlights some of the challenges that need to be addressed in the current scenario to improve their performances in controlled and real-time situations.
