MECH4460: Design of Micro- and Nanosystems
2025 unit information
This unit teaches the student how to recognize where and how their theoretical skills can be applied to practical situations in the field of mechanical design. As a case study, a set of widely implemented Micro-Electro-Mechanical Systems (MEMS) is introduced, including Pressure Sensors, Microphones, Accelerometers, Gyroscopes and Micromirrors. Selected mechanical designs are presented and design choices are discussed with respect to their performance. Notions specific to microfabrication and the concept of scaling laws are introduced and elucidated at commonly implemented examples. The unit includes a hands-on design and modelling part introducing modern multi-physics finite element analysis. Dedicated tutorial sessions introduce the finite element modeling of Micro-Electro-Mechanical Systems. An emphasis is laid on the capability to couple multiple physics in a single model, including deformation of solids by electrostatic, electromagnetic or electro-thermal forces. The students will learn how to conceive and engineer a MEMS design, and predict performance by multi-physics finite element analysis.
