Soft Bio‐Microrobots: Toward Biomedical Applications
Advanced Intelligent Systems, Volume 6, Issue 2, February 2024.Soft bio‐microrobots are created with designs inspired by living creatures or utilizing motile microorganisms or cells. Their compliant and flexible bodies enable them to adapt to intricate environments. This review presents a summary of the design principles, energy sources, and biomedical applications of soft bio‐microrobots. The challenges that must

Symplectic and antiplectic waves in an array of beating cilia attached to a closed body [PDF]
Phys. Rev. E 95, 052412 (2017), 2016 By taking into account the hydrodynamic interactions in a one dimensional array of model cilia attached to a no-slip cylinderical surface, we investigate their synchronized motion. We show, how does the emergence of metachronal waves depend on the initial state of the system and investigate the conditions under which, the formation of symplectic and ...

Structured light enables biomimetic swimming and versatile locomotion of photoresponsive soft microrobots. [PDF]
, 2016 Microorganisms move in challenging environments by periodic changes in body shape. In contrast, current artificial microrobots cannot actively deform, exhibiting at best passive bending under external fields.

Metachronal Waves in Cellular Automata: Cilia-Like Manipulation in Actuator Arrays [PDF]
, 2014 Paramecium is covered by cilia. It uses the cilia to swim and transport food particles to its mouth. The cilia are synchronised into a collective action by propagating membrane potential and mechanical properties of their underlying membrane and the liquid phase environment.

Hydrodynamic flow patterns and synchronization of beating cilia
, 2006 We calculate the hydrodynamic flow field generated far from a cilium which is attached to a surface and beats periodically. In the case of two beating cilia, hydrodynamic interactions can lead to synchronization of the cilia, which are nonlinear ...

Respiratory Cilia as a Therapeutic Target of Phosphodiesterase Inhibitors
Frontiers in Pharmacology, 2020 Mucociliary clearance is an essential airway defense mechanism dependent predominantly on the proper ciliary function and mucus rheology. The crucial role of cilia is evident in `a variety of respiratory diseases, as the ciliary dysfunction is associated

Functional imaging of mucociliary phenomena: High-speed digital reflection contrast microscopy [PDF]
, 2018 We present a technique for the investigation of mucociliary phenomena on trachea explants under conditions resembling those in the respiratory tract. Using an enhanced reflection contrast, we detect simultaneously the wave-like modulation of the mucus ...
