The hydrodynamic Euler-elastica: shape transitions in the dynamical buckling of elastic filaments in Stokes flow
Clément Moreau, Laetitia Giraldi, Hermes Bloomfield-Gadêlha
The buckling of elastic filaments in viscous fluids, ubiquitous in biological systems like flagella, microtubules, and DNA, has long been described by the static Euler-elastica. Ye…
Optimal Control of Microswimmers for Trajectory Tracking Using Bayesian Optimization
Lucas Palazzolo, Mickaël Binois, Laëtitia Giraldi
Trajectory tracking for microswimmers remains a key challenge in microrobotics, where low-Reynolds-number dynamics make control design particularly complex. In this work, we formul…
Harnessing swarms for directed migration of interacting active particles via optimal global control
Chiara Calascibetta, Laëtitia Giraldi, Jérémie Bec
This study investigates the use of global control strategies to enhance the directed migration of swarms of interacting self-propelled particles confined in a channel. Uncontrolled…
Two-way Coupling of Fluid--Structure Interaction for Elastic Magneto-Swimmers:A Finite Element ALE Approach
Christophe Prud'Homme, Vincent Chabannes, Laëtitia Giraldi +2
Artificial micro-swimmers actuated by external magnetic fields hold significant promise for targeted biomedical applications, including drug delivery and micro-robot-assisted thera…
Non-Locally Controllable but Trackable Magnetic Head Flagellated Swimmer
Lucas Palazzolo, Mickaël Binois, Laëtitia Giraldi
Unlike macroscopic swimmers, microswimmers operate in a low-Reynolds-number regime dominated by viscous forces. This paper investigates the controllability of a magnetic microswimm…
Parametric Shape Optimization of Flagellated Micro-Swimmers Using Bayesian Techniques
Lucas Palazzolo, Laëtitia Giraldi, Mickael Binois +1
Understanding and optimizing the design of helical micro-swimmers is crucial for advancing their application in various fields. This study presents an innovative approach combining…
