4.2. Principles of MEMS Design

Try these first

1. 1.

   What is one design objective for MEMS devices?

   Hint

   Think about what the device is expected to do.

2. 2.

   Name one design constraint that affects MEMS design.

   Hint

   Consider what might limit the materials you can use.

3. 3.

   What is a key objective of MEMS design?

   • Minimizing weight
   • Maximizing cost
   • Increasing size

   Hint

   Think about why lightweight materials are preferred in small devices.

4. 4.

   True or False: Fabrication processes can affect the design constraints.

   • True
   • False

   Hint

   Consider how different processes might limit design options.

5. 5.

   A MEMS design project calls for a sensor that needs to operate in high temperatures and harsh chemicals. Discuss how you would approach material selection for this project.

   Hint

   Consider what happens to materials at elevated temperatures.

6. 6.

   You are tasked with designing a MEMS device that includes moving parts. Discuss the potential challenges and constraints you might face during the design process.

   Hint

   Think about the implications of small-scale mechanics.
