Flexible iontronic pressure sensors have attracted extensive attention in intelligent robots and wearable healthcare devices for their flexible properties sensing functions. Introducing surface microstructures has remarkably enhanced sensitivity, whereas achieving with high sensitivity over a broad linear range remains challenging. Here, we propose hierarchical synergetic strategy by combining hemisphere porous microstructure, realizing (9.27 kPa-1), fast response speed (<15 ms), (R2 =...
Abstract The bonding formation for ultrasonic welding of dissimilar metals has been shrouded in mystery because the complex thermomechanical behavior at interface. We investigated microstructure and phases interface ultrasonically welded aluminum to copper joints using transmission electron microscopy, found a ~10 nm thick transition layer composed amorphous phase nanocrystallines, which was believed form between these two addition mechanical interlocking observed larger scale....
Ultrasonic welding is a well-known technique for joining thermoplastics and has recently been introduced to carbon fiber-reinforced composites (CFRC). However, suitable models predicting joint performance have not yet established. At present, most failure bonded are built based on uniform adhesive joints, which assume constant properties. Nevertheless, the properties of ultrasonic spot welds CFRC variable, depend input parameters. In this paper, effect energy, important parameter,...
An integrated experimental and computational approach has been adopted to investigate the formation mechanism of intermetallic compounds (IMCs) in dissimilar Al-Cu joints processed by vaporizing foil actuator welding (VFAW). Aiming understand IMCs their transition, present work employed first-principles calculations thermodynamic properties as a function temperature pressure together with diffusivities Al Cu from literature. Agreeing observations, predicted IMC sequence low-energy region is...
This work proposes a novel flexible manipulator consisting of series 2-DOF vertebrae based on ball-and-socket joint that is connected by ball-shaped surface and cup-shaped socket constrained pins for circumferential rotation. can demonstrate outstanding torsional stiffness since the rotation between four ball pins. The point contact guideways effectively reduces friction vertebrae, thus allowing designed to yield smooth bending shape with constant curvature. features high axial stiffness,...
Ultrasonic welding is a robust and cost-effective joining method. It can be applied to of metals, polymers composites. Several approaches have been used in the identification relationships between input parameters ultrasonic (e.g., energy, time) joint strength, including experimental methods finite element based prediction. Both these two are accurate but require long lead time for model development. The empirically identified may very complex accuracy prediction sensitive variations...
The piston-returning spherical joint pair in an axial piston pump continuously bears alternating loads generated by conversions between high and low pressure. If its strength fails, then the cannot function normally. Therefore, we performed numerical simulations laboratory experiments to investigate properties of components pump. results show that when is transition area from oil suction discharge, maximum deformation stress slipper are located on inner surface socket, value 2.523 μm. When...
Most classification efforts for primary subtypes of lung adenocarcinoma (LUAD) have not yet been integrated into clinical practice. This study explores the feasibility combining deep learning and pathomics to identify tumor invasiveness in LUAD patients, highlighting its potential value assisting junior intermediate pathologists. We retrospectively analyzed whole slide image (WSI) data from 289 patients with surgically resected ground-glass nodules (GGNs). First, three ResNet models were...
Cervical spinal cord injury is often catastrophic, frequently leading to irreversible impairment. MRI has become the gold standard for evaluating injuries (SCI). Our study aimed assess accuracy of a radiomics approach, based on machine learning and utilizing conventional MRI, in predicting prognosis patients with SCI. In retrospective analysis 82 SCI from three hospitals, we categorized them into good (n = 49) poor 33) groups. Preoperative T2-weighted images were segmented using 3D-Region...
Asphalt pavement will inevitably produce internal distresses during service, which increases the risk of deterioration structural performance. Although three- dimensional ground penetrating radar (3D GPR) with a multi-channel antenna array can detect condition asphalt non-destructively and quickly, there is currently lack effective evaluation index standard. In this paper, 3D GPR was used to investigate four typical existing in Guangzhou- Shaoguan Expressway, including cracks, loose,...
Continuum manipulators can manipulate objects in complex environments and conform to curvilinear paths, which makes it emerging be applied minimally invasive surgery.
