An Innovative Concept: Free Energy Harvesting Through Self-Powered Triboelectric Nanogenerator

Abstract

Globally, the internet of things (IoT) is a concept for the realization, integration, and updating of both the physical and digital world through the use of sensors to obtain accurate data from the environment triboelectric nanogenerators (TENG) are shown to be promising for applications involving self-powered sensors and mechanical energy harvesting. Traditional triboelectric generators harvest energy in contact mood but are not cost-effective. Therefore, in this research article, we report on the design and development of a simple, robust, cost-effective, and novel TENG, which can provide a maximum power of around 9.89 μW at an external load resistance of 85 MΩ. The fabricated TANG has a maximum open-circuit voltage of 54 V and a short circuit current of 61 μA. As a proof of concept, capacitors of different ratings were charged and 30 LEDs (Light-emitting diode) were powered up through the fabricated TENG. Output results show that the many commercial electronic devices such as a smartwatch, calculator, Remote Keyless Entry (RKE), temperature sensor, pressure sensor and so many low current operating sensors can be powered up through the fabricated self-powered triboelectric nanogenerator.

Effect of calcium carbonate nanoparticles on mechanical properties of coir-kenaf based epoxy hybrid composites: An analytical and simulation study

“…The hybrid composite is studied to predict water absorption and mechanical features with differing weight percent of fiber content [24]. It is also observed that the hybrid effect of fibers enhanced the overall performance and composite attributes [26,68]. Composite with two different fibers, used in the proportion of 25 percent Coir and 75 percent Kevlar, inculcated good impact, flexural, and water absorption properties.…”

“…Some fibers like hemp, pineapple, sisal, and kenaf show similar properties compared to steel and aluminum [6,[57][58][59][60][61]. Because of the innumerable and positive characteristics of natural fibers, the utilization of composites made by these fibers shows their wide range of uses in areas of vehicle, construction, aircraft, and marine industries [7][8][9][10][11][62][63][64][65][66][67][68]. Despite these numerous pros of NFCs, some cons need to be observed, such as low impact strength, high rate of water absorption, and lower heating capacity.…”
