Scaling in MEMS
MICRO-606
This file is part of the content downloaded from Scaling in MEMS.
This doctoral class covers the scaling of MEMS devices, including mechanical, thermal, electrostatic, and microfluidic aspects.
Topics
- Introduction to scaling laws: scaling of classical mechanical systems, scaling of classical electrical systems, breakdown in scaling, quantum breakdown.
- Mechanical scaling: mass-spring model, mechanical noise, squeeze film effects.
- Thermal scaling: conduction, convection, dynamics, breakdown, thermal micro-actuators.
- Microfluidic scaling: liquid flow, gas flow, diffusion-mixing, surface tension,
- Electrostatic scaling: parallel plate actuators, zipping actuators, electrostatic breakdown
- Piezo-scaling
Grading: Students will make a presentation analyzing how scaling laws influence the design, performance, and limitations of one specific MEMS device.
you will:
- Learn how scaling-related effects differ in different physical domains
- be able establish
simple scaling rules
- understand examples where scaling effects are exploited
- Be able to select an appropriate actuation/sensing principle adapted to your size
