Recent advances in cellulose-based flexible triboelectric nanogenerators

The gorgeous transformation of paper: from cellulose paper to inorganic paper to 2D paper materials with multifunctional properties

“…Therefore, the application range of paper-based materials has expanded to paper-based flexible electronics. Actually, cellulose paper has been prosperously developed in flexible electronic devices including sensors, 91 nanogenerators, 32,92 supercapacitors, 93–95 transistors, 96–98 actuators, 99–102 photodetectors, 103–105 and synthetic gene networks. 106 In this section, we will choose to display paper-based humidity and strain/pressure sensors, which make up a small portion of paper-based flexible electronic devices, to show the natural characteristics and unique advantages of cellulose paper, and further illustrate the multi-functional applications of cellulose-based paper.…”

Recent Advances on Conducting Polymers Based Nanogenerators for Energy Harvesting

“…The development of highly porous composites and nanostructured CPs over the last few decades has resulted in a wide range of applications that benefit from their ease of fabrication, scalability, highly porous structures, super-lightweight nature, moderate mechanical properties, and large surface areas [19]. They have been investigated as new functional composites in water remediation [113], liquid transport [114], electronic devices [115], supercapacitors [116], and other applications [117]. Very recently, researchers found that the incorporation of porous structure into TENGs can create a new way for the production of TENGs.…”

“…Due to the flexibility of ES-TENG, it may be utilized on a variety of flexible object surfaces, including gloves, clothing, pillows, and shoes, to gather irregular and random mechanical energy. Cellulose-based materials have been used in flexible energy harvesting and storage systems since of their low density, elasticity, ease of manufacture, large specific area, and superior mechanical characteristics [117,121]. Because of its high oxygen content, cellulose appears to have lost electrons and is efficiently positively charged, making it a promising positive material for polymer-based environmentally friendly TENGs [122], for example, Cellulose-based materials have been used in flexible energy harvesting and storage systems since of their low density, elasticity, ease of manufacture, large specific area, and superior mechanical characteristics [117,121].…”

Electrospray Deposition of Cellulose Nanofibers on Paper: Overcoming the Limitations of Conventional Coating

“…From the academic perspective, despite numerous articles (mainly published from 2010 to today) that have involved CMNFs in some form [ 4 , 5 ], the field is still full of uncertainties with respect to potential applications. The possibilities seem endless, from reinforcement of structural materials [ 6 ], to providing all kinds of electronic devices, such as transistors and nanogenerators [ 7 , 8 ], with flexibility and transparency. From the industrial perspective, the nanocellulose market is expected to increase at an annual growth rate of up to 21.3% [ 9 ].…”
