DESIGN, CHARACTERIZATION and VISUALIZATION of MICRO SWIMMERS INSIDE CHANNELS
Micro swimming robots have great potential in biomedical applications such as targeted drug delivery, medical diagnosis, and destroying blood clots in arteries. . Many in vivo systems like human circulatory system, urinary system and central nervous system are suitable for medical processes performed by micro robots. Inspired by micro swimming organisms, micro robots can move with helical tails attached to their body. Although there are many experimental and modeling studies can be found in literature about examining the motion of micro organisms, the behavior of swimming micro robots in channels is not yet well understood. In order to design and navigate micro robots, the characteristics of flows generated by micro swimmers need to be understood in detail, in terms of characterizing the behavior of swimming micro robot with respect to swimming parameters, such as helical pitch, helical tail radius and the rotation frequency; determining the effects of position of the robots inside channel with experiments and Computational Fluid Dynamics (CFD) models; and analyzing the effect of rotational frequency to controlling of speed and position of micro swimmers. In addition micro Particle Image Velocimetry (μPIV) is planned to be used to visualize the trajectory of the micro robot inside a channel and analyze the flow induced by the motion of the helical tail.
