Development and application of stereo camera-based upper extremity workspace evaluation in patients with neuromuscular diseases. [PDF]

PLoS ONE, 2012
BackgroundThe concept of reachable workspace is closely tied to upper limb joint range of motion and functional capability. Currently, no practical and cost-effective methods are available in clinical and research settings to provide arm-function ...

3D Printing of Bacteriophage‐Loaded Hydrogels: Development of a Local and Long‐Lasting Delivery System

Advanced Healthcare Materials, EarlyView.
This research investigates the feasibility of 3D‐printing of a bacteriophage‐containing hydrogel made of alginate and methylcellulose. The printed hydrogels steadily release active bacteriophages for up to 35 days which is beneficial to treat implant‐associated infections.

Full-Color See-Through Three-Dimensional Display Method Based on Volume Holography

Sensors, 2021
We propose a full-color see-through three-dimensional (3D) display method based on volume holography. This method is based on real object interference, avoiding the device limitation of spatial light modulator (SLM).

Synthetic Cell‐Based Tissues for Bottom‐Up Assembly of Artificial Lymphatic Organs

Advanced Healthcare Materials, EarlyView.
Synthetic cells have emerged as a novel biomimetic approach for fundamental research and therapeutic interventions. T cell activating synthetic cells are able to form 3D tissue‐like structures by self‐assembly into lymphatic bottom‐up tissues (lymphBUT) with tunable biochemical and biomechanical functionalities as well as metabolic activity are ...

A Novel Simulation Method for 3D Digital-Image Correlation: Combining Virtual Stereo Vision and Image Super-Resolution Reconstruction

Sensors
3D digital-image correlation (3D-DIC) is a non-contact optical technique for full-field shape, displacement, and deformation measurement. Given the high experimental hardware costs associated with 3D-DIC, the development of high-fidelity 3D-DIC ...

Fibrillar Bundles as Fibrous Filler Materials for Attaining Cell Anisotropy in Bioprinting

Advanced Healthcare Materials, EarlyView.
Fibrillar bundles are introduced as a bioprintable additive that enables robust and scalable cellular alignment within 3D constructs through flow‐induced orientation during extrusion. These fibers support strong cell adhesion and polarization across various cell types and significantly enhance myotube alignment in Gelatine‐Methacryloyl (GelMA ...

DiCE [PDF]

ACM Transactions on Graphics, 2019
In stereoscopic displays, such as those used in VR/AR headsets, our eyes are presented with two different views. The disparity between the views is typically used to convey depth cues, but it could be also used to enhance image appearance. We devise a novel technique that takes advantage of binocular fusion to boost perceived local contrast and visual ...
