Designing Fluid-Exuding Cartilage for Biomimetic Robots Mimicking Human Joint Lubrication Function [PDF]

The human joint is an open-type joint composed of bones, cartilage, ligaments, synovial fluid, and joint capsule, having advantages of flexibility and impact resistance. However, replicating this structure in robots introduces friction challenges due to the absence of bearings.

A Bio‐Inspired Perspective on Materials Sustainability

Advanced Materials, EarlyView.
This perspective discusses natural materials as inspiration for sustainable engineering designs and the processing of materials. First, circularity, longevity, parsimony, and activity are presented as essential material paradigms. The perspective then uses many examples of natural and technical materials to introduce principles such as oligo ...

Hydrogel‐Impregnated Robust Interlocking Nano Connector (HiRINC) for Noninvasive Anti‐Migration of Esophageal Stent

Advanced Materials, EarlyView.
The development of hydrogel‐impregnated robust interlocking nano connector (HiRINC) aims to address stent migration by improving tissue adhesion and reducing mechanical mismatch in self‐expandable metallic stents (SEMSs). The network‐like porous layer of HiRINC enhances adhesion and energy dissipation, demonstrates through ex vivo and in vivo tests ...

Multi-Channel Volumetric Neural Network for Knee Cartilage Segmentation in Cone-beam CT [PDF]

, 2019
Analyzing knee cartilage thickness and strain under load can help to further the understanding of the effects of diseases like Osteoarthritis. A precise segmentation of the cartilage is a necessary prerequisite for this analysis. This segmentation task has mainly been addressed in Magnetic Resonance Imaging, and was rarely investigated on contrast ...

Structured Light Projection Using Image Guide Fibers for In Situ Photo‐biofabrication

Advanced Materials, EarlyView.
Light‐based biofabrication is typically performed with single wavelength light sources and within benchtop devices. This work demonstrates FaSt‐Light (Fiber‐assisted Structured Light) as a new approach to achieve multiwavelength image projection using flexible image guide fibers, which enables a variety of applications for in situ biofabrication ...
