| Abstract: | Given complexity of the design and manufacturing processes of microelectromechanical system (MEMS) products, we present a
unified modeling language (UML) based design approach for multi-domain products or systems like MEMS to designing and evaluating
possible solutions at the early design stage to shorten their development time. Specifically, the proposed approach is used
to model and analyze a novel drug delivery system combining MEMS devices and integrated circuit (IC) units. This drug delivery
system aims to be used for safer and more effective therapy of the diabetics. Two design models about the whole drug delivery
system and its micropump subsystem are established using UML diagrams; in particular a composition diagram with components
and ports describes the topology of the system. Through design and simulation on the micropump subsystem, it is found that
the variations of geometrical dimension and excitation voltage affect the characterization of the micropump. The simulation
results demonstrate and validate the proposed approach, and can be used as a significant reference for the designer to design
the optimal micropump. |
