Abstract The monitoring of currents in the abyssal ocean is an essential foundation deep-sea research. state-of-the-art current meter has limitations such as requirement a power supply for signal transduction, low pressure resistance, and narrow measurement range. Here, we report fully integrated, self-powered, highly sensitive system which ultra-sensitive triboelectric nanogenerator harvests energy self-powered sensing tiny motions down to 0.02 m/s. Through unconventional magnetic coupling structure, withstands immense hydrostatic exceeding 45 MPa. A variable-spacing structure broadens measuring range 0.02–6.69 m/s, 67% wider than that commercial alternatives. successfully operates at depth 4531 m South China Sea, demonstrating record-deep operations nanogenerator-based sensors environments. Our results show promise sustainable with higher spatiotemporal resolution.

Abstract The monitoring of micro‐droplets parameters is significant to the development droplet microfluidics. However, existing methods have drawbacks such as high cost, interference with movement, and even potential for cross‐contamination. Herein, a method (MDMM) based on liquid‐solid triboelectric nanogenerator (LS‐TENG) proposed, which can realize non‐invasive self‐powered in microfluidic chip. frequency monitored by voltage pulse mathematical model established monitor length velocity.

Abstract Accurate measurement of complicated multiphase flow is crucial to the safety and efficiency petroleum chemical industrial facilities. However, existing detection techniques are not applicable pipelines in remote regions including deserts or deep seas, due high cost providing a stable power supply. Herein, self‐powered sensor, composed liquid‐driven triboelectric nanogenerator (TENG) ‐based signal generator, ring‐type transmitter, string‐type receiver, proposed. Theoretical modeling displacement current between transmitter receiver implies that received can accurately reflect wetting state validated by combined experimental (accuracy above 97%) simulation study. Coupling with quantitative analysis algorithm, system numerous points developed precisely monitor various parameters, slug frequency (one point), length (two points), pattern (four which verified spontaneous high‐speed camera recordings water–air flow.

Abstract Triboelectric nanogenerator (TENG) has received significant attention as an energy harvesting technology capable of converting mechanical from the environment into electrical power. However, due to its inherent high impedance and low charge transfer output characteristics, TENG is often relatively small. Current research typically focuses on switching off under intrinsic voltage for performance management. To further improve performance, management strategy proposed that aimed at boosting in this study. This ingeniously designs discharge sequence two switches adjust connection between capacitor matched capacitor, thereby facilitating instantaneous voltages surpassing significantly enhancing power density. Combining with a converter enhanced storage efficiency capacitors, enabling improved supply sensor devices. Moreover, experimental results show density 324.8 kW m − 2 , indicating 100% increase compared direct strategy. With such power, five parallel 10‐watt commercial lamps can be illuminated. introduces novel idea achieving TENG.
