Abstract
This thesis is mainly focused on the fundamental research of self assembly which
includes studying the concept of self assembly, necessary ingredients for a successful
self assembly and the various principles of self assembly. First, the existing concepts
of self assembly systems using different interactions such as gravitational force,
capillary force, electrical force and magnetic force are included in the literature research
and then summarized to give an overview of the applications of self assembly. After
choosing a proper principle which is magnetic forces for demonstrating the concept of
self assembly, the analysis of the force and the manipulation of the force is then
described in detail. The goal of this paper is to understand and develop concepts for
magnetic self assembly. The concept of magnetic self assembly is demonstrated with
different test structures. The test structures are designed with different amount of
magnets, distinct geometry, reduced degree of freedom due to confined motion on
liquid surface or a combination of them. These features of the test structure are aimed
to demonstrate how the behavior of magnetic self assembly are affected. Lastly, three
different test structures are developed and embedded with magnets as the source of
interaction. They are the octahedron, puzzle-like and hexagon structures with an
emphasis on the puzzle-like structures. The experiments with different level of the
puzzle-like structures presented a 90% and 100% yield of successful self assembly
respectively. Through hierarchical self assembly, the successful self assembly of the
desired end aggregate is demonstrated.
