Abstract Triboelectric nanogenerator (TENG) is a promising technology, which can convert biokinetic energy into electricity and be utilized as self‐powered sensors power sources for wearable electronics. The existing designs of conventional TENGs require complex fabrication processes device structures, they need to attached on human body application, uncomfortable may lead malfunction under intense moment. Here, direct current TENG proposed by utilizing natural body, basketball, shoes,...
Abstract The direct detection of light polarization poses a crucial challenge in the field optoelectronics and photonics. Herein, tunable linear dichroism (LD) GeSe‐based polarized photodetectors is presented through electronic structural asymmetry modulation, demonstrate their application prospects wearable electronics. An improvement dichroic ratio up to 34% achieved under gate voltage 20 V, reaches 44% by applying tensile strain along zigzag direction. Theoretical calculations reveal that...
Charge and spin are two intrinsic attributes of carriers governing almost all the physical processes operation principles in materials. Here, we demonstrate manipulation electronic states designed Co-quantum dot/WS2 (Co-QDs/WS2) heterostructures by employing a metal–dielectric composite substrate via scanning tunneling microscope. By repeatedly under unipolar bias, switching bias polarity, or applying pulse through nonmagnetic magnetic tips, Co-QDs morphologies exhibit regular reproducible...
Residual stress in aluminum alloy affects the mechanical performance of material. The effective evaluation residual state (RSS) including directions and values principal stresses is great concern. This article attempts to test RSS by eddy current (EC) method, which has characteristics nondestructive, noncontact, reliable. approach involves solving forward problem inverse problem. establish relation between EC responses terms response surfaces determine with measured signals based on...
Interlayer excitons, with prolonged lifetimes and tunability, hold potential for advanced optoelectronics. Previous research on the interlayer excitons has been dominated by two-dimensional heterostructures. Here, we construct WSe2/GaN composite heterostructures, in which doping concentration of GaN twist angle bilayer WSe2 are employed as two ingredients manipulation exciton behaviors polarizations. The energies monolayer can be regulated continuously levels substrate, a remarkable increase...

Through the analysis interpretation large amount data platforms, study reveals positive information dissemination, increased participation, problem feedback By providing convenient channels for exchange public effectively improved decision-making process effect article also deeply studies interaction mechanism between planning media, discusses strategies based puts...
Image stitching is a traditional but challenging computer vision task. The goal to stitch together multiple images with overlapping areas into single, natural-looking, high-resolution image without ghosts or seams. This article aims increase the field of view gastroenteroscopy and reduce missed detection rate. To this end, an improved depth framework based on unsupervised panoramic gastrointestinal tract proposed. In addition, preprocessing for aberration correction monocular endoscope...
The objective of this research was to investigate the effects material models, element types, and boundary conditions on consistency finite analysis. Two cantilever beams were used; one made stainless steel SUS301 3/4H other polymer polyoxymethylene. load–deflection curves two obtained by experiments compared those analysis, where models—including bilinear, trilinear, multi-linear—were used. Four types—beam, plane stress, shell, solid—were also employed with models obtain simulated beams. It...
Aiming at the shortcomings of traditional gap sensor, measurement accuracy is greatly affected by environmental factors such as temperature, and a levitation method based on image processing designed. The high-speed industrial camera monitors in real time transmits to PC. processed PC obtain value gap, which can complete function sensor. experimental results show that has high precision fast speed, meet stability control requirements ball system.
Abstract In recent years, underground pedestrian system (UPS) has been developed worldwide, especially within central megacity areas, but research on UPS characteristics is still in the qualitative description stage, and quantitative methods are lacking to assess impact of resilience. Therefore, it essential quantitatively measure resilience thus be able make decisions how can improved. The authors propose topological analysis networks based computational functional graph representations,...
Multilayer metallic plate is made by stacking homogeneous or heterogeneous plates and connecting them with fasteners. The air-gap thickness between the adjacent layers affects performance of structure. eddy current testing (ECT) technology has been used for nondestructive multilayer plate. However, effect air gap on characteristics (EC) attenuation in remains unclear study relation response EC probe very limited. computation results paper show that a double-layer reduces amplitude density...
The influence of temperature, vibration time, amplitude, and other factors on the residual stress release effect was studied using method low-temperature heating high-frequency ultrasonic vibration, excellent control parameters were obtained. In addition, cutting weld reinforcement also studied. results demonstrate that highest relative rate 280.29%, average over 150 MPa, efficiency higher than general methods. After reinforcement, only a small part released, influencing overall distribution...
