Abstract Mimicking living creatures, soft robots exhibit incomparable adaptability and various attractive new features. However, untethered insect-scale are often plagued with inferior controllability low kinetic performance. Systematically inspired by the swift swingable abdomen, conducting canals for secretion transport, body setae of Stenus comma , together magnetic-induced fast-transformed postures, herein, we present a swift, agile millimetre-scale propulsor propelling on water. The...

By incorporating soft materials into the architecture, flexible mechanical metamaterials enable promising applications, e.g., energy modulation, and shape morphing, with a well-controllable response, but suffer from spatial temporal programmability towards higher-level intelligence. One feasible solution is to introduce snapping structures then tune their responses by accurately tailoring stress-strain curves. However, owing strongly coupled nonlinearity of structural deformation material...

Convective Polymerase Chain Reaction (cPCR), owing to its enhanced thermal cycling efficiency, holds promise for application in the next generation of mainstream commercial PCR instruments. Despite potential, existing capillary-based and annular reaction chamber designs encounter limitations precisely controlling internal flow field, which poses a significant barrier progression cPCR. To overcome these obstacles, this work innovatively proposes cPCR chip utilizing “racetrack-shaped” chamber,...

Soft pneumatic actuators (SPAs) are extensively investigated due to their simple control strategies for producing sophisticated motions. However, the motions or operations of homogeneous SPAs show obvious limitations in some varying curvature interaction scenarios because profile mismatch and specific interacted objects. Herein, a stiffness preprogrammable soft actuator (SPSPA) is proposed by discretely presetting gradient geometrical materials distributions. Through finite element analysis...

High-performance tactile sensors are urgently demanded in various intensive interactive scenarios, e.g., texture detection, robotic interaction with fragile objects, and motion direction recognition, where dynamic conditions involved complex tangential forces or vibrations. Although many microstructured/porous can perceive forces, their isotropic structures that lack programmability lead them to be incapable of sensing the restrain tunability for situations, a wide range large high...

Distinguished by its exceptional sensitivity and specificity, Polymerase Chain Reaction (PCR) is a pivotal technology for pathogen detection.

Clinical data of 2 cases with Rosai-Dorfman disease(RDD) originating from nasal septal mucosa were reported retrospectively,and the pertinent literature was reviewed. Without specific clinical features,RDD in cavity could be misdiagnosed easily. Pathology revealed different morphologies cell proliferation engulfed lymphocytes,plasma cells and neutrophils. Immunohistochemical staining showed S-100(+),CD68(+)，CD1(-).RDD disease generally has a benign course is self-limited. Its diagnosis...

The approximate k-Nearest Neighbor (kNN) graph has been proved extremely useful in nearest neighbor search (ANNS). However, under the high-dimensional and large-scale circumstance, performance of is challenging due to its high costs distance calculation. To solve problem, most approaches focus on pruning edges during phase construction. In our observation, searching a given query an even well pruned kNN graph, large proportion can be cut-off procedure. this paper we propose concept Direction...
