Fast Hydrogel Micro‐Actuators Driven by Electric Fields
Advanced Materials, EarlyView.We report the fabrication of chemically programmable electroactuating microstructures through the first integration of two‐photon polymerization with electrically actuated gelatin methacrylate‐based hydrogels. By tailoring the charge of the polymer network, we demonstrate programmable polarity‐dependent bending, enabling microstructures that ...

An Active Balancer of Currents for Bipolar DC Power Grids
2025 IEEE Seventh International Conference on DC Microgrids (ICDCM)DC power grids (DCPGs) are gaining more significance, predominantly due to the natural DC operation of technologies such as renewables, energy storage systems, and electric vehicles. Particularly, thanks to power electronics, bipolar DCPGs are gaining more preponderance since they enable reducing power losses, increasing power density, and averting ...
