The coefficient of thermal expansion (CTE) architected materials, as opposed to that conventional solids, can be tuned zero by intentionally altering the geometry their structural layout. Existing material architectures, however, achieve CTE tunability only with a sacrifice in efficiency, i.e. drop both stiffness mass ratio and strength ratio. In this work, we elucidate how resolve trade-off between efficiency present lightweight bi-material architecture not is stiffer stronger than other 3D...
Abstract This paper presents thermally actuated hierarchical metamaterials with large linear and rotational motion made of passive solids. Their working principle relies on the definition a triangular bi-material unit that uses temperature changes to locally generate in its internal members distinct rates expansion translate into anisotropic motions at level deployment global scale. Obtained from solid mechanics theory, thermal experiments fabricated proof-of-concepts numerical analysis,...
A photothermal synergy mechanism for recycling unavailable heat to improve light energy utilization and reduce the cured threshold during NIR photopolymerization 3D printing efficiency based on UCAP.
Disabilities impacting mobility are a global concern requiring gait rehabilitation, where monitoring foot pressure distribution is fundamental. Wearable systems provide an alternative to stationary equipment eliminating space limitations. However, wearable sensors present challenges in the calibration, sensitivity, and human–sensor interface, application-specific sensors. This study aimed develop sensors, structural material properties can characterize sensitivity range of measurement during...
In this work, an anomalous thick oxide-degradation phenomenon in n-type 650-V class super-junction VDMOS transistors is investigated. An unexpected threshold voltage (Vt) decrease was observed with high positive bias temperature instability stress, and the saturation current (IDsat) increases stress time. Repeatable reproducible behaviors have been achieved from multiple devices under test. Based on simulation experimental results, it found that high-energy electrons (caused by gate voltage)...
Stress concentration is a crucial source of mechanical failure in structural elements, especially those embedding voids. This paper examines periodic porous materials with porosity lower than 5%. We investigate their stress distribution under planar multiaxial loading, and presents family geometrically optimized void shapes for mitigation. adopt generalized description both geometry tessellation patterns that can handle single multiple voids arbitrary shape at generic angle. The role...
