On the transport of epididymal fluid induced by the metachronal wave of cilia

Journal of Engineering Mathematics, 2018
In this study, we investigate the propulsion mechanism of cilia involved in the flow of epididymal material through the ductus efferentes. Assuming that the rheological characteristics of the material behave as a micropolar fluid, we formulate a mathematical model for the axially symmetric flow through a cylindrical tube whose inner surface is covered ...

Development of Micro Pump Using Magnetic Artificial Cilia with Metachronal Wave

2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS), 2020
Our study aims to realize artificial cilia with metachronal wave and to apply them to a micro pump. Metachronal wave is a typical motion observed in natural cilia motion of living organisms.

Dynamics of a magnetically rotated micro swimmer inspired by paramecium metachronal wave.

Progress in Biophysics and Molecular Biology, 2019
In the past few years, a significant body of research has been devoted to designing magnetic micron scale robotic systems for minimally invasive medicine. The motion of different microorganisms is the nature's solution for efficient propulsion of these swimmers.

Ciliary metachronal wave propagation on the compliant surface of Paramecium cells

Cytoskeleton, 2015
Ciliary movements in protozoa exhibit metachronal wave‐like coordination, in which a constant phase difference is maintained between adjacent cilia. It is at present generally thought that metachronal waves require hydrodynamic coupling between adjacent cilia and the extracellular fluid.

Metachronal wave of artificial cilia array actuated by applied magnetic field

Japanese Journal of Applied Physics, 2016
Abstract In this paper, a biomimetic microstructure related to cilia, which are effective fluidic and conveying systems in nature, is described. Authors have already reported that a magnetic elastomer pillar actuated by a rotating magnetic field can work like a natural cilium. In the present work, we show examples of a cilia array with a

In vivo dynamic quantitative imaging of cilia metachronal wave in mouse fallopian tube with optical coherence tomography

BiOS, 2023
Motile cilia are hair-like microtubule-based organelles covering epithelial surfaces of multiple organ systems, including lungs, airways, kidneys, and fallopian tubes.

Metachronal wave form analysis on cilia-driven flow of non-Newtonain Phan–Thien–Tanner fluid model: A physiological mathematical model

Proceedings of the Institution of mechanical engineers. Part E, journal of process mechanical engineering, 2022
The Phan–Thien–Tanner non-Newtonian model of fluid flow is considered to mathematically model the cilia governed flow inside the human body. The collective action of cilia generates a rhythmic motion in form of metachronal wave traveling along the wall ...

A comparative study of MHD fluid-particle suspension induced by metachronal wave under the effects of lubricated walls

International Journal of Modern Physics B, 2021
In this paper, the two-phase flow of non-Newtonian fluid is investigated. The main source of the flow is metachronal waves which are caused by the back and forth motion of cilia attached to the opposite walls of the channel. Magnetohydrodynamics (MHD) of

Metachronal ciliary wave motion analysis on peristaltic flow of hyperbolic tangent nanofluid through an inclined magnetic field in a symmetric channel

International Journal of Modelling and Simulation, 2023
The phenomenon of metachronal wave of artificial cilia activated by the influence of magnetic field has many biological applications. The main aim of the present investigation is to show the effect of magnetic field on peristaltic-ciliary flow of ...
