Abstract:This thesis is about the influence of a dynamic flow field on microbots controlled by a static magnetic field. First of all it is important to know what the relevance of the research is. In the current situation anticoagulants are used to help solve thrombosis. This has a couple of unwanted side effects, such as jaundice and excessive bleeding. To solve thrombosis another way there are researches like these. In this research magnetic actuation controlled microbots are used. Therefore the magnetic actuation is explained and modelled to get a theoretical answer. After that, there are experiments done to test the theory and look into the physical limits of the used technology. From these experiments we can draw the conclusion that the microbots which are controlled by a static magnetic field can move through a low dynamic flow field when the actuation frequency ranges between 1 and 10Hz. All the experiments are done in water with the flow rates 0, 5, 10, 15 and 20mL min−1. To get a better view of the limits of this technology further research need to be done. There is a need to look at more actuation frequencies to determine the step out frequency and it is useful to look at higher flow rates and different microbots.
