Abstract With the development of wearable electronics, use engineered functional inks with printing technologies has attracted attention owing to its potential for applications in low‐cost, high‐throughput, and high‐performance devices. However, improvement conductivity stretchability mass production is still a challenge practical applications. Herein, scalable efficient fluid dynamics process that produces highly stretchable, conductive, printable containing high concentration graphene...
Abstract Li‐metal is gaining attention as a next generation anode active material, of which the primary attribute its energy density. However, Li dendrite formation challenge. Herein, design strategy with increased structural dimensions and hierarchy for investigated to stabilize extending cycle life high reversibility. For this, diverse current collectors (CCs) are fabricated by manipulating in different length scales characterized anode. The (i.e., nanostructures inside microcavities) can...
Stretchability and areal coverage of active devices are critical design considerations stretchable or wearable photovoltaics photodetections where high coverages required. However, simultaneously maximizing both properties in conventional island-bridge structures through traditional two-dimensional manufacturing processes is difficult due to their inherent trade-offs. Here, a 3D printer-based strategy achieve extreme system stretchability combining fused deposition modeling (FDM) flexible...
The SAD (safety and arming device) is an indispensable fuse component that ensures safe reliable performance during the use of ammunition. Because application electronic devices for smart munitions increasing, miniaturization has become one key issues next-generation artillery fuses. Based on MEMS technology, various types miniaturized SADs have been proposed fabricated. However, none them reported to used in actual due their lack high impact endurance complicated explosive train...
We introduce a metallic high-efficiency particulate air (HEPA) filter based on Cu nanofiber membrane, which grasps matters physically and electrostatically. The also shows excellent antimicrobial property reusability.
The electrospraying of water in the cone-jet mode is difficult practical applications owing to its low throughput and electrical discharge caused by high surface tension water. A film with multiple dielectric micronozzles essential for multiplexed without discharge. Thus, a pyramidal micronozzle five nozzles was fabricated using UV-embossing process. consisted micronozzles, micropillar array, an in-plane extractor, which were proposed minimize wetting concentrate electric field meniscus at...
Current transformers (CTs) are essential components to measure system current for safe operation and protection of railway substations. Many studies have been conducted related low-power (LPCTs) meet increasing demand digitalization This study proposes a newly developed LPCT replace conventional CTs in gas-insulated switchgears (GISs) The prototype consisted Rogowski sensor (RCS) passive module; it was designed an output 150 mV at the rated 1250 A according IEC 61869-10. also assembled metal...
A dielectric polymer micro atomizer was fabricated and performed cone jet mode electrospray of water without electrical discharge. high aspect ratio nozzle an in-plane extractor were proposed to concentrate electric field at the tip which prevents discharge in ambient air. pillar array also prevent from wetting during electrospray. Cone visualized by using a nanosecond pulsed laser illumination.
Structural Current Collectors In article number 2202321, Jae Young Seok, Sanha Kim, and co-workers introduce a structurally hierarchical copper current collector for lithium metal battery anodes. The nanorods inside the micro-cavities concentrate local electrical field onto inner surfaces of microstructures, enabling inward nucleation lithium. subterraneously grown tends to agglomerate, resulting in minimized solid-electrolyte interface formation suppression dendrite formation, thus,...
Surface-enhanced Raman spectroscopy (SERS) is a high-sensitivity, label-free detection method that shows promise for various analytical applications. Hydrophobic low-adhesion surfaces make excellent SERS substrates since they allow the usage of trace analytes at low concentrations by efficiently enriching them into SERS-active region. Herein, we introduce hydrophobic surface-enhanced scattering substrate based on engineered carbon nanotube arrays (CNT-SERS) and study role structural design...
