Miniaturizing machines and physical systems is an ongoing effort in human civilization. This effort has been intensified in recent years as market demands for: Intelligent, Robust, Multi-functional and Low cost consumer products has become stronger than ever. The only solution to produce these consumer products is to package many components into the product – making it necessary to miniaturize each individual component. Miniaturization of physical systems is a lot more than just scaling down device components in sizes.
Types of Scaling Laws
1) Scaling in Geometry: Scaling of physical size of objects
If we let l= linear dimension of a solid, we will have:
2) Scaling of Phenomenological Behavior: Scaling of both size and material characterizations
From particle kinematics, we have:
where vo= the initial velocity. By letting vo= 0, we may express:
Thus, the scaling of dynamic force, F is
