Abstract Artificial tactile perception systems that emulate the functions of slow adaptive (SA) and fast (FA) cutaneous mechanoreceptors are essential for developing advanced prosthetics humanoid robots. However, constructing a high‐performance sensory system within single device capable simultaneously perceiving both static dynamic forces surface‐texture recognition remains critical challenge; this contrasts with common strategies integrating individual SA‐ FA‐mimicking sensors in multi‐layered, multi‐circuit configurations. Herein, textile pressure/tactile (PT) sensor is reported based solely on piezoresistive principle alongside high sensitivity rapid response to high‐frequency vibrations forces. These characteristics attributed sensor's 3D multiscale architecture corresponding hierarchical structural deformation its honeycomb‐like sensing fabric. As proof‐of‐concept application relevant robotics prosthetics, an automated surface‐texture‐recognition constructed by PT machine‐learning algorithms, prosthetic device, industrial robot arm, graphical user interface. This artificial demonstrates ability learn distinct object features, differentiate fine surface textures, subsequently classify unknown textiles accuracy (>98.9%) across wide range scanning speeds (50–300 mm s −1 ). results show promise future development interactive intelligence.

Microreactors have the advantages of high heat and mass transfer efficiency, strict control reaction parameters, easy amplification, good safety performance, been widely used in various fields such as chip manufacturing, fine chemicals, biomanufacturing. However, narrow microchannels microreactors often become filled with catalyst particles, leading to blockages. To address this challenge, study proposes a multiphase flow model based on lattice Boltzmann method (LBM) investigate dynamic changes during bubble collapse process temperature distribution regularities. Based developed three-phase dynamics model, delves into shock evolution analyzes Then, patterns under different particle density conditions are explored. The found that action wave, stable structure liquid film is destroyed, deforms collapses. At moment collapse, energy rapidly transferred from potential kinetic field. Subsequently, converted pressure waves. This results rapid generation extremely field, creating high-velocity jets intense turbulent vortices, which can enhance effects flows. certain phenomenon will be formed at region relatively chaotic random. waves generated significant impact motion trajectories while influence high-density particles small. offer theoretical basis for understanding mechanisms flow. Moreover, these findings practical implications advancing technologies industrial applications, including manufacturing chemical transport.

With the rapid development of new energy vehicle market, demand for efficient, low-noise, low-energy consumption, high-strength, and durable gear transmission systems is continuously increasing. Therefore, it has become imperative to conduct in-depth research into fluid heat transfer lubrication dynamics within gearboxes. In systems, interaction between fluids solids leads complex nonlinear characteristics gears lubricants, making resolution gearbox thermodynamic models highly challenging. This paper proposes a model based on LBM-LES coupling study dynamic laws process. The results indicate that intense shear effects caused by high speeds generate vortices, which are particularly pronounced larger gears. mixing effect in these vortex regions better, achieving more uniform dissipation effect. Furthermore, flow lubricant closely related speed temperature. Under high-temperature conditions (such as 100 °C), diffusion range increases, forming wider oil film, but its viscosity significantly decreases, leading greater stirring losses. By optimizing selection lubricants parameters, efficiency reliability system can be further improved, extending service life. provides comprehensive analytical framework multi-stage clarifying mechanisms offering insights theoretical foundations future engineering applications this field.

Tactile sensors are the cornerstone of modern technology development by mimicking human tactile perception and providing precise diverse mechanical feedback for cutting-edge fields such as robotics, medical equipment, virtual reality. However, current research predominantly concentrates on monitoring normal forces. How to accurately recognize decouple multidirectional force pairs remains a challenge. To this end, we design sensor modifying cuprous oxide (Cu2O) surface zinc nanorods (ZnO NRs) arrays integrating it with transverse force-to-vertical conversion structure. As result, modification boosts piezoelectric output ZnO sensitivity 17.25 nA MPa-1, which is about 3 times higher that pure ZnO. The mechanism underlying enhancement illustrated from perspective surface-engineered heterojunction. On basis, ability detect forces verified prototype, can monitor in 12 directions over 360° range. This work provides new strategy designing sensors, showing broad application prospect human-machine interaction beyond.
