4.2.2. Design Constraints

Try these first

1. 1.

   What is the main consideration when selecting materials for MEMS?

   Hint

   Think about how materials perform differently at smaller dimensions.

2. 2.

   Give one example of a fabrication method used in MEMS.

   Hint

   Recall the methods mentioned in the chapter.

3. 3.

   What is a key constraint in MEMS design related to materials?

   • A. Unlimited material choices
   • B. Limited material properties
   • C. Enhanced mechanical properties

   Hint

   Think about how properties change when scaling down.

4. 4.

   True or False: Fabrication process compatibility does not affect MEMS design.

   • True
   • False

   Hint

   Consider the implications of mismatch.

5. 5.

   Design a microscale temperature sensor informed by the constraints of material properties, fabrication processes, and electrical effects. Justify your choices.

   Hint

   Consider common temperature sensing techniques and how constraints influence design.

6. 6.

   Analyze how a MEMS accelerometer might fail if thermal expansion is not accounted for in its design and suggest a mitigation strategy.

   Hint

   Think about real-life applications of accelerometers.
