“…The OCV value decreases as the operating distance increases because of the well-known Coulomb's law. 40 It should be emphasized that the OCV of our TFS is clearly dependent on the periodic hand movement even at an operating distance of 30 cm without using an external power supply. In contrast, the operating distances of the TFS reported previously were as short as a few centimeters.…”

The rise in environmental issues has stimulated research on alternative energy. In this regard, triboelectric generation has received much attention as one of several new alternative energy sources. Among the triboelectric generation methods, solid-liquid triboelectric nanogenerators (SLTENGs) have been actively investigated owing to their durability and broad applicability. In this paper, we report on the optimum arrangement of SLTENGs to increase the generation of electrical energy. When hydrophobic SLTENGs are arranged in parallel with a specific intervening gap, the friction area between the water and the surface of the SLTENGs is changed owing to the different penetration distances of water between them. This difference affects the amount of triboelectricity generated; this change in the water contact area is caused by the capillary phenomenon. Therefore, we investigated the effect of the gap on water penetration and formulated an optimum arrangement to achieve optimum electricity generation efficiency when multiple SLTENGs are contained in a limited volume. The proposed optimum arrangement of SLTENGs is expected to have high utilization in energy harvesting from natural environment sources such as wave energy or water flow.In this study, we developed an arrangement of TENGs that allows the most efficient energy output within a limited volume by considering the capillary effect. First, the gap between parallel-stacked solid-liquid TENGs (SLTENGs) that generates the maximum electrical output was investigated. Next, we analysed whether this optimal value of the gap is effective when the number of electrodes is varied within the limited volume. Through experimentation, the optimal arrangement of SLTENGs in a limited volume was determined for sustainable and increased electricity generation. The proposed arrangement can be regarded as a guide for increasing the electrical output of liquid-driven TENGs. Experimental SectionMaterials.

To eliminate the impurities and unevenness that influence contact electrification on industrial aluminium plates, the plates were polished in a mixture of perchloric acid and ethyl alcohol (HClO 4 : C 2 H 5 OH = 1: 4 by volume) under a constant voltage of 20 V for 5 min using a computer power supply (Digital Electronics Co., DRP-92001DUS). The mixture was maintained at 7 °C during the polishing process by means of a circulator (Lab Companion, RW-0525G). After the polishing process, the plates were rinsed w...

“…In different fields, researchers have applied TENGs to collect different environmental energies such as mechanical vibration energy, [21][22][23] wind energy, [24,25] ocean current energy [26] and wave energy, [27] and realized self-powered sensing of vibration, [28,29] wind speed, [30] gas and liquid flow velocity, [31] tactile, [32] tilting angle [33] and gas composition [34] based on TENG technology. In the field of drilling, a series of studies have been carried out in the areas of down hole vibration and rotation [35,36] energy collection, and self-powered vibration monitoring. [37] However, the installation of these devices will inevitably affect the normal operation of the drill pipe, because they are arranged outside of the drill pipe.…”

Measurement while drilling (MWD) system of offshore drill pipe is of great significance for safety production. It is greatly demanded to develop a sustainable power supply as well as self‐powered sensors for the MWD system. In this work, a drill pipe‐embedded annular type triboelectric nanogenerator (AT‐TENG) is proposed and systematically investigated, and it consists of an annular silicone rubber and a pair of electrodes. The design of the AT‐TENG allows the silicone rubber to contact and separate with the electrodes easily in a narrow space under arbitrary direction vibration to realize power generation. The experimental results show that the peak power density of AT‐TENG with single‐pair electrode reaches 63.7 W m−3 under the vibration frequency of 4 Hz and amplitude of 100 mm. The minimum peak voltage is >65 V within 360° lateral vibration range. The peak voltage achieves 351.62 V under the third‐order natural frequency. In addition, the amplitude and frequency obtained from the voltage signals exhibit linearly with those of actual vibration. The mean error between the frequency detected by AT‐TENG and actual frequency is <0.03%. Thus, the AT‐TENG can serve as an energy harvester and self‐powered vibration sensor.
