Jigsaw Pattern Infills Inspired by Toughening Mechanisms of Diabolical Ironclad Beetle for 3D Printing Technologies

Advanced Materials Technologies, EarlyView.
A biomimetic Jigsaw pattern infill for 3D printer has been developed. Its mechanical features with continuous carbon fiber reinforcement (CCFR) are investigated through the Design of Experiments. The Jigsaw infill minimizes mechanical strength losses caused by variability in infill density, flow rate, or carbon fiber string amount, outperforming ...

Internal fixation of S1-S3 iliosacral screws and pubic screw as the best configuration for unstable pelvic fracture with unilateral vertical sacral fracture (AO type C1.3)

Journal of Orthopaedic Surgery, 2017
Background: Although internal fixation is the definitive treatment in unstable pelvic fractures with disruption of the anterior arch and a vertical fracture of the sacrum (AO type C1.3), there have been no agreement of the best technique of internal ...

Microneedles From Shape‐Preserving Crosslinked Poly(Vinyl Alcohol) Hydrogels: Minimising Interference in Transdermal Proteomics

Advanced Materials Technologies, EarlyView.
Hydrogel‐forming microneedle patches are developed using shape‐preserving PVA‐PVP hydrogels, with and without chitosan, for minimally invasive transdermal protein biomarker sampling. The optimised patches enable efficient interstitial fluid uptake and proteomic analysis, while minimising interference.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.

Recent Advances in Variable‐Stiffness Robotic Systems Enabled by Phase‐Change Materials

Advanced Robotics Research, EarlyView.
Phase‐change materials (PCMs), such as shape memory alloys, hydrogels, shape memory polymers, liquid crystal elastomers, and low‐melting‐point alloys, are driving advancements in stiffness‐tunable robotic systems across a wide range of applications. This review highlights recent progress in PCM‐enabled robotics, focusing on their underlying mechanisms,

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Delayed migration of K-wire into popliteal fossa used for tension band wiring of patellar fracture

Chinese Journal of Traumatology, 2013
【Abstract】Breakage of K-wires and stainless steel wires which are used for fracture fixation is not uncommon, but migration is rare. We report a case of migration of bro-ken K-wire used for patella tension band wiring to the popliteal fossa.
