Thermomechanics of Picoliter Liquids Encapsulated in Metal Microarchitectures

Advanced Materials, Volume 38, Issue 17, 20 March 2026.
Picoliter‐scale water is encapsulated inside hollow copper microcylinders through a single‐step localized electrodeposition process. Mechanical testing at room and cryogenic temperatures reveals that incompressible liquid and load‐bearing microscale ice enhance the strength and deformation behavior of the composite structure.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, Volume 13, Issue 15, 13 March 2026.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Controlled Interfacial Stress Platform for Electrochemical‐Mechanical Coupling Measurements

Advanced Energy Materials, Volume 16, Issue 9, 4 March 2026.
Understanding electrochemical‐mechanical coupling in solid‐state batteries is vital for predicting their performance, degradation, and safety. Conventional screw‐jig platforms provide data but lack insights into stress effects on individual couplings.

Enhanced Operation Mode Design and Motion Control of a Dual-Redundancy Electro-Hydrostatic Actuator

Actuators
In dual-redundancy electro-hydrostatic actuators (EHAs), the dual pumps are mainly designed for safety, where the cylinder is controlled mainly by one pump while the other one is standby for redundancy. However, such a strategy is basically like a single-

A Novel Contact‐Implicit Trajectory Optimization Framework for Quadruped Locomotion without Fixed Contact Sequences

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Legged robots have advanced in environmental interaction through contact, but most works rely on fixed contact sequences. This work presents a new method based on an indirect optimization method for legged robots to automatically generate contact sequences for complex movements.

The impact of healthy motion seating on lower‐limb blood flow and blood pressure response to simulated long‐haul air travel

Experimental Physiology, Volume 111, Issue 3, Page 1513-1523, 1 March 2026.
Abstract Prolonged sitting inherent to long‐haul air travel can acutely decrease lower‐limb blood flow and increase brachial blood pressure. Healthy motion seating (HMS), which passively alters sitting interface pressure and posture, is a promising technology which may attenuate the deleterious effects of long‐haul air travel. The aim of this study was
