Abstract The anti‐glare panels along highways can block the dazzling lights of opposing vehicles at night, playing an important role in highway safety. Inspired by panels, wind energy harvesting triboelectric nanogenerator (AG‐TENG) arrays to properly capture from moving is developed. A single AG‐TENG installation module achieve a high power density 0.2 Wm −2 speed 3 m s −1 . This too low drive conventional equipment. performance shows no degradation after 80 h continuous operation (1 440...
Abstract Existing technologies for harvesting electrical energy from gentle wind face an enormous challenge due to the limitations of cut‐in and rated speed. Here, a leaf‐like triboelectric nanogenerator (LL‐TENG) is proposed that uses contact electrification caused by damped forced vibration topology‐optimized structure consisting flexible leaf, vein bearing plate, counterweight piece. The effectiveness studied, which solves problem reduced output electrostatic adsorption between leaf...
Abstract The tribovoltaic effect is the direct‐current (DC) output that results from sliding a p‐type semiconductor on top of an n‐type semiconductor, and it caused by electron–hole pairs generated However, rigid structure traditional limits its potential application in wearable fields. Here, p–type n–type fabric with properties are prepared doping small organic molecules cetyltrimethylammonium bromide sodium dodecylbenzene sulfonate carbon atoms single–wall nanotubes (SWCNTs), three...
Real-time monitoring of flow turbulence is very difficult but extremely important in fluid dynamics, which plays an role flight safety and control. Turbulence can cause airflow to detach at the end wings, potentially resulting aerodynamic stall aircraft causing accidents. Here, we developed a lightweight conformable system on wing surface for sensing. Quantitative data about degree boundary layer separation are provided situ using conjunct signals by both triboelectric piezoelectric effects....
Abstract Shelter forests (or shelter‐belts), while crucial for climate regulation, lack monitoring systems, e.g., Internet of Things (IoT) devices, but their abundant wind energy can potentially power these devices using the trees as mounting points. To harness energy, an omnidirectional fluid‐induced vibration triboelectric nanogenerator (OFIV‐TENG) has been developed. The device is installed on shelter forest to harvest from all directions, employing a (FIV) mechanism (fluid‐responding...
Abstract The rise of Internet Things and wearable healthcare electronics has prompted the rapid development pressure sensors. A novel developing trend focuses on a sensor with high sensitivity over wide range, multifunction, breathability, excellent wearing comfort, which remains challenge. To address these issues, an all‐fabric device is designed by loading Ti 3 C 2 T x MXene nanosheets onto woven fabrics through simple dip‐coating method sewing three fabric layers different coating...
In recent years, the two-dimensional material MXene has shown great advantages in field of wearable electronics and pressure sensors. Toward advanced applications, achieving a conformal sensor with ultrathin thickness flexibility through simple preparation principle, while maintaining its high sensitivity wide detection range, is still key challenge for development high-performance Herein, we proposed an optimized mild LiF/HCl etching scheme successfully achieved high-concentration (>25...
Lenz’s law states that the change in magnetic flux over time induces an electromotive force around a circuit, commonly referred to as rule. However, exceptions “flux rule” were discussed by Richard Feynman The Lectures on Physics 1963. anti-flux phenomenon occurs when there is large-size and rotating metal medium present circuit. This has attracted attention of many researchers, although most studies have predominantly focused theoretical mathematical calculations. Here, we designed...
Abstract Bionic structures are widely concerned in flexible sensors. However, there is a lack of research on the optimization structure to improve performance. Herein, two types plant leaves with quite different surface structures, rose petal (RP) and paper mulberry (PM) leaf, used fabricate an asymmetric complementary structure. Under pressure, microcones PM can insert into grooves RP microdome be bended under high pressure. Compared that PM–PM RP–RP space for increasing internal contact...

Abstract The accuracy and efficiency of shooting reports constitute indispensable cornerstones in modern military training fields. However, traditional report systems struggle to offer precise sensitive instant feedback, especially rare scenarios, such as multiple piercing shots on the ring boundaries. Simultaneously, ballistic analysis a pivotal approach criminal investigations, confronts similar challenges including high costs, complex data processing, strong professional dependency. Thus,...
