Passive Janus particles are self-propelled in active nematics
New Journal of Physics, 2022 While active systems possess notable potential to form the foundation of new classes of autonomous materials (Zhang et al 2021 Nat. Rev. Mater. 6 437), designing systems that can extract functional work from active surroundings has proven challenging. In

Self-propulsion simulation of DARPA suboff [PDF]
, 2017 Hydrodynamic performance prediction of a propeller working behind a submerged body is a popular research field. For a submarine propeller, the propeller-hull interaction should be considered during the preliminary design stage. In this study, the resistance and propulsion analyses of the well-known bench-mark DARPA Suboff with E1619 propeller have been

Theoretical model of chirality-induced helical self-propulsion [PDF]
Physical Review E, 2018 We recently reported the experimental realization of a chiral artificial microswimmer exhibiting helical self-propulsion [T. Yamamoto and M. Sano, Soft Matter 13, 3328 (2017)1744-683X10.1039/C7SM00337D]. In the experiment, cholesteric liquid crystal (CLC) droplets dispersed in surfactant solutions swam spontaneously, driven by the Marangoni flow, in ...

4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing
Advanced Functional Materials, EarlyView.A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Pattern formation in self-propelled particles with density-dependent motility
, 2012 We study the behaviour of interacting self-propelled particles, whose self-propulsion speed decreases with their local density. By combining direct simulations of the microscopic model with an analysis of the hydrodynamic equations obtained by explicitly

Fish biorobotics: kinematics and hydrodynamics of self-propulsion [PDF]
Journal of Experimental Biology, 2007 SUMMARYAs a result of years of research on the comparative biomechanics and physiology of moving through water, biologists and engineers have made considerable progress in understanding how animals moving underwater use their muscles to power movement, in describing body and appendage motion during propulsion, and in conducting experimental and ...

Sensorized Engineered Tissues with Built‐in Thermoregulation and Nutrient Supply
Advanced Functional Materials, EarlyView.This work introduces a granular hydrogel‐based tissue engineering platform that includes a closed‐loop temperature control to maintain 37°C and sustainably releases nutrients, thereby enabling cells to retain a high viability even if stored at room temperature for up to 24 h.

Noncentral forces mediated between two inclusions in a bath of active Brownian rods
Scientific Reports, 2021 Using Brownian Dynamics simulations, we study effective interactions mediated between two identical and impermeable disks (inclusions) immersed in a bath of identical, active (self-propelled), Brownian rods in two spatial dimensions, by assuming that the

Load response of shape-changing microswimmers scales with their energy efficiency
, 2018 External forces acting on a microswimmer can feed back on its self-propulsion mechanism. We discuss this load response for a generic microswimmer that swims by cyclic shape changes.
