Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

A tubular electrowetting pump moves alternating droplets through a millimeter‐wide channel in discrete, reversible steps, functioning as a fluidic stepper motor. With no moving parts and electrodes insulated from the liquid, it delivers silent, accurate flow. Flexibility allows the pump to be woven directly into textiles for wearable, medical, and soft‐

Transient stability analysis and enhancement of wind farm integrated VSC-HVDC system
Following severe faults in wind farm integrated voltage source converter (VSC) based high-voltage direct current (HVDC) system, wind turbines (WTs) may lose synchronization with wind farm side VSC (WFVSC), which jeopardizes the reliable delivery and ...

Wearable Kirigami‐Apertured Capacitive Sensors for Continuous Cardiac Volumetric Monitoring
A wearable kirigami‐apertured carbon nanotube‐paper composite (K‐CPC) capacitive sensor enables cardiac volumetric monitoring. The kirigami process creates a central aperture with cantilevered fibers that confine the electric field, enhancing both sensitivity and lateral resolution.

Bioprinting High‐Cell‐Density Cardiac Tissue Constructs With Sustained Contractile Function
Contractile cardiomyocytes in 3D culture provide insights into the behavior of the heart. Combining a 3D bioprinting approach with a multi‐electrode array allows the development of the 3D culture to be monitored over time, and matured cultures allow the effect of drugs on cardiac function to be modelled, replicating effects seen in clinical application.
