Velocity and Out-Step Frequencies for a Micro-Swimmer Based on Spiral Carbon Nanotubes

The existing producing processes of micro spiral swimmers are complex. Here, a microswimmer with magnetic layer on the surface carbon nanotubes is proposed, which has simple process. For microswimmer, its equations velocities and out-step frequency deduced. Using these equations, their changes related parameters investigated. Results show that proportional to radius helix angle nanotubes, frequencies field strength, thicknesses inversely fluid viscosity. measured, in good agreement calculative ones.
