Hydrodynamics can determine the optimal route for microswimmer navigation

A Daddi-Moussa-Ider, H Löwen, B Liebchen - Communications Physics, 2021 - nature.com
As compared to the well explored problem of how to steer a macroscopic agent, like an
airplane or a moon lander, to optimally reach a target, optimal navigation strategies for …

[HTML][HTML] Reinforcement learning of a multi-link swimmer at low Reynolds numbers

K Qin, Z Zou, L Zhu, OS Pak - Physics of Fluids, 2023 - pubs.aip.org
The use of machine learning techniques in the development of microscopic swimmers has

Self-organized swimming with odd elasticity

K Ishimoto, C Moreau, K Yasuda - Physical Review E, 2022 - APS
We theoretically investigate self-oscillating waves of an active material, which were recently
introduced as a nonsymmetric part of the elastic moduli, termed odd elasticity. Using …

Controllability and Optimal Control of Microswimmers: Theory and Applications

C Moreau - Journal of the Physical Society of Japan, 2023 - journals.jps.jp
The process of swimming at the microscopic scale is successfully described as a finite-
dimensional, nonholonomic control system due to negligible inertia in the low-Reynolds …

Purcell's swimmer in a shear-thinning fluid

K Qin, OS Pak - Physical Review Fluids, 2023 - APS
Locomotion of biological and artificial microswimmers has received considerable attention

Energy-optimal strokes for multi-link microswimmers: Purcell's loops and Taylor's waves reconciled

F Alouges, A DeSimone, L Giraldi, Y Or… - New Journal of …, 2019 - iopscience.iop.org
Micron-scale swimmers move in the realm of negligible inertia, dominated by viscous drag
forces. In this paper, we formulate the leading-order dynamics of a slender multi-link (N-link) …

Optimization and small-amplitude analysis of Purcell's three-link microswimmer model

O Wiezel, Y Or - Proceedings of the Royal Society A …, 2016 - royalsocietypublishing.org
This work studies the motion of Purcell's three-link microswimmer in viscous flow, by using
perturbation expansion of its dynamics under small-amplitude strokes. Explicit leading-order …

Purcell's swimmers in pairs

R Attanasi, M Zoppello, G Napoli - Physical Review E, 2024 - APS
We investigate the effects of hydrodynamic interactions between microorganisms swimming
at low Reynolds numbers, treating them as a control system. We employ Lie brackets …
