Summary: Flexible ferromagnetic filaments can be used to control micro-scale flow with an external magnetic field. This study proposes a method using the shape of a ferromagnetic filament in a rotating field to determine its magnetoelastic number, which can then be used to determine the bending modulus. The method is found to have a higher accuracy compared to other estimation methods.

Summary: Researchers have developed an on-demand micromixer based on magnetic microwalls, which can achieve controllable mixing and complete mixing shut-off in commercial microfluidic devices. The microwalls can create a meandering path in the main channel to enable mixing or open up the channel to stop mixing, controlled by a simple magnet. Experimental results show that the microwalls can effectively enhance mixing in colored fluids with different flow rates and viscosities.

Summary: The study demonstrates that a thermally actuated double pendulum can exhibit a metachronal motion using a self-propulsion mechanism caused by spontaneous asymmetrical heat transfer. By using a multiple pendulum structure with beams of different lengths, phase differences can be produced among the beams. This device has potential applications in biomedical microfluidic systems or microrobots in water.

Summary: Microalgae have shown great potential as a source of biofuels, food, and other bioproducts. The study demonstrated that growth can be enhanced by ten and two times with hydrophobic and hydrophilic MAC, respectively, compared with control groups. This technique can be easily adopted in labs without microfabrication infrastructures and can benefit screening studies.

Summary: This work proposes a strategic path for addressing the mechanical wear problem in sliding mode triboelectric nanogenerators (TEGs) by incorporating ferromagnetic tribo-medium into a flexible cilium structure. Contrary to the conventional notion, the ferromagnetic cilia based TEG (FC-TEG) achieved its highest output at the critical contact/noncontact state. Experimental findings demonstrate that TEG and electromagnetic generator (EMG) exhibit a mutually complementary relationship in coordinating motion frequency and electrical output.

Summary: This study uses computational simulation to investigate the swimming kinematics and induced flow field dynamics of jellyfish-inspired soft robotic swimmers. The researchers explore the kinematic performance of the jellyfishbot through a parametric sweep of different system parameters. They find that applying an appropriate magnetic field and controlling the remnant magnetization profile can enhance the temporal and spatial asymmetries in the soft magnetic composite elastomeric lappets, leading to improved swimming speed.
