Effect of metachronal waves
In this chapter we study the effect of metachronal waves on the flow created by magnetically-driven artificial cilia in microchannels. We use a coupled magnetomechanical solid-fluid model that captures the physical interactions between the fluid flow, ciliary deformation and applied magnetic field. When a rotating magnetic field is applied to super-paramagnetic artificial cilia, they mimic the ...
متن کاملMetachronal propagation of motor activity.
A diverse array of biomechanical systems has evolved to satisfy locomotor requirements (reptation, swimming, walking, etc.) and in all cases, successful behabior achievement requires the integrated functioning of various segments, to ensure the appropriate positioning of the different body regions. From comparative studies on a variety of invertebrate and vertebrate organisms, it is now establi...
متن کاملMetachronal Wave Gait Generation for Hexapod Robots
The metachronal wave is a gait used by most terrestrial arthropods. Each leg only lifts when the leg behind it is on the ground in position to support the animal’s weight. The wave starts from the back as the hind leg lifts and is transferred forward as each leg in turn lifts. At its fastest, it is the tripod gait. In its slowest smooth movement form, only one leg at a time is lifted on each si...
متن کاملEmergence of metachronal waves in cilia arrays.
Propulsion by cilia is a fascinating and universal mechanism in biological organisms to generate fluid motion on the cellular level. Cilia are hair-like organelles, which are found in many different tissues and many uni- and multicellular organisms. Assembled in large fields, cilia beat neither randomly nor completely synchronously--instead they display a striking self-organization in the form ...
متن کاملInjection and extraction magnets: kicker magnets
Each stage of an accelerator system has a limited dynamic range and therefore a chain of stages is required to reach high energy. A combination of septa and kicker magnets is frequently used to inject and extract beam from each stage. The kicker magnets typically produce rectangular field pulses with fast riseand/or fall-times, however, the field strength is relatively low. To compensate for th...
