In Situ Two‐Dimensional Residual Stress Characterization of Thin Films

open access: yesAdvanced Materials Technologies, EarlyView.
An integrated in situ curvature metrology platform combining speckle‐based curvature optical metrology (SCOM) with multi‐beam optical sensors (MOS) enables spatially resolved two‐dimensional curvature mapping of thick sputtered coatings. The SCOM technique provides excellent agreement with MOS while providing an extended measurable curvature range ...

Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

open access: yesAdvanced 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.

Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

open access: yesAdvanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Hybrid Additive Manufacturing of Highly Stretchable Bottlebrush Polymer Nanocomposites by Decoupled Extrusion and Photopatterning

open access: yesAdvanced Materials Technologies, EarlyView.
A Hybrid Direct Ink Writing–Digital Light Processing (HDD) strategy decouples material extrusion from shape definition, enabling high‐fidelity additive manufacturing of highly viscous, yield‐stress polymer nanocomposites. Excess ink acts as a removable, self‐supporting scaffold, allowing fabrication of unsupported and embedded complex architectures ...

Assessment of Asthma in Geriatric Patients Using the Forced Oscillation Technique

open access: yes
Background: Asthma is prevalent among older adults; however, its assessment is often incomplete due to limited use of spirometry, partly because poor patient cooperation in this age group.

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications

open access: yesAdvanced Materials Technologies, EarlyView.
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...
