Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems
Advanced Materials Technologies, EarlyView.Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Advanced Optical Materials, EarlyView.Multifunctional fluorescent coatings offering simultaneous thermo‐ and mechanochromic‐time integration via Förster resonance energy transfer (FRET) are reported. The exchange of fluorophores among donor and acceptor droplets in the coatings over time results in a decrease in the average intermolecular distance between the donor–acceptor pair, yielding ...

On–Off Switchable Micromotors for Use in Steerable Microvehicles
Advanced Robotics Research, EarlyView.Electrically controllable micromotors and microvehicles are developed by tuning the diffusion of the fuel. Self‐propelled micromotors using bubble propulsion show great promise for miniaturized devices with multiuse purposes such as cargo delivery and sensing. However, there is currently no method to electrically switch the micromotors on or off. Here,

Verification of a Novel Method of Detecting Faults in Medium-Voltage Systems with Covered Conductors
Metrology and Measurement Systems, 2017 This paper describes the use of new methods of detecting faults in medium-voltage overhead lines built of covered conductors. The methods mainly address such faults as falling of a conductor, contacting a conductor with a tree branch, or falling a tree ...
