3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

Advanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

Advanced Materials Technologies, EarlyView.
A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

Assessing Rip Current Occurrences at Featureless Beaches Using Boussinesq Modeling

Journal of Marine Science and Engineering
Rip currents at featureless beaches (i.e., beaches lacking sandbars or channels) are often hydrodynamically controlled, exhibiting intermittent and unpredictable behaviors that pose significant risks to recreational beach users.

Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

Advanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Development and evaluation of a rip current forecasting system for channel-type rip currents on a low-energy headland beach

Geomatics, Natural Hazards & Risk
A 34-day field observation was conducted on a headland beach in South China with a typical channel rip current system. The Delft3D model was applied to reproduce hydrodynamic conditions and extract rip currents, while a Generalized Additive Model (GAM ...

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Rips, Currents and Snags

Australian and International Journal of Rural Education, 2012
Monash University (Gippsland campus) is situated in Churchill, Latrobe Valley, located in central Gippsland, eastern Victoria. A large percentage of the Gippsland region comprises of a socio-economically disadvantaged population (Figure 1). In Semester One, 2011 as part of the Bachelor of Primary Education course at Monash, it was decided that a ...
