I am currently working on designing a specific micro-machine which is immersed
in viscous fluid.This is being modeled assuming Stokes flow. The micro-machine
consists of a head and a moving "rigid" tail. The tail either can oscillate in
the vertical plane or it may rotate conically. Using the previous work done on
micro-organisms, I found out that rigid tail does not produce any effective
movement.

I am looking for someone who may have modeled similar micro-machine. Also
introducing me to any recent research related to this problem would be greatly
appreciated.
