A rotational switched-mode water-based triboelectric nanogenerator for mechanical energy harvesting and vehicle monitoring

Electric Power Generated from Magnetic Nanofluid Droplets Sliding upon Superslippery Surfaces

“…As shown in Figure 4d, the change of the electric current in the device can be detected when the arm moves up and down. The current value could exceed 6 μA, which surpasses current values generated by previous liquidbased generators 22,23,31,32 based on the triboelectric principle. Moreover, the current is also higher than that of other triboelectric 33−36 and piezoelectric devices, 37−40 primarily due to the low internal resistance of the magnetoelectric devices in this study.…”

Progress in techniques for improving the output performance of triboelectric nanogenerators

“…251 One of their key features is the ability to convert the continuous release of electric energy from the TENG into an instantaneous release. [263][264][265] Moreover, the operation frequency of the travel switch is directly related to the output frequency of TENGs, i.e., the working frequency of the travel switch is generally 1-2 times as high as the output frequency of electrical signals. 266 For example, Zi et al 267 added charging cycles and motion trigger switches to a TENG system, which enhanced the maximum energy storage efficiency by 50% and increased the saturation voltage by at least 2 times.…”

Recent progress towards smart transportation systems using triboelectric nanogenerators

“…This technology possesses distinct benefits and unique properties that make it highly suitable for this purpose. There has been a growing proliferation of research groups proposing the utilization of TENG in the development of autonomous sensing systems capable of harnessing energy for application in automobiles [108][109][110][111][112][113][114][115][116][117].…”
