This file is part of the content downloaded from Scaling in MEMS.

Summary

This doctoral class covers the scaling of MEMS devices, including mechanical, thermal, electrostatic, electromagnetic, 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
Students will make a presentation analyzing how scaling laws influence the design, performance, and limitations of one specific MEMS device.
