Advanced Functional Materials, EarlyView.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‐

3D Hydrodynamic Flow Lithography
Advanced Functional Materials, EarlyView.ABSTRACT Continuous‐ and stop‐flow lithography are widely used to fabricate multi‐dimensional microstructures whose cross‐sectional morphology is dictated by the flow profile of multiple co‐flowing streams. Here, we introduce three‐dimensional hydrodynamic flow lithography (3D HFL), a platform for programmable generation of multi‐layered flow profiles ...

Advanced Functional Materials, EarlyView.A CMOS‐compatible, all‐dielectric Silicon‐on‐Glass reflective metasurface enables low–loss terahertz wavefront control for future 6G wireless communication. Mie‐resonant silicon pillars provide full phase coverage near 500 GHz, achieving experimentally validated single‐, dual‐, and five‐beam steering with sub‐1.5° angular error and less than 3 dB ...

Characteristics of the Radiating Element of a Planar Vivaldi Antenna Array with Improved Bandwidth
Известия высших учебных заведений России: РадиоэлектроникаIntroduction. The conventional approach to extending the operating frequency band of Vivaldi antenna arrays consists in increasing the radiating element length. However, this inevitably leads to an increase in the mass of the entire array, and, therefore,

Advanced Functional Materials, EarlyView.A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.
