Highly recommended for any engineer looking to transition into MEMS design or students requiring a practical, code-based introduction to the field.
For those interested in inertial sensors, designing a MEMS accelerometer or a vibratory rate gyroscope is an excellent challenge. For instance, designing a 2-DOF (degree-of-freedom) vibratory rate gyroscope pushes you to understand and implement complex mechanical coupling and vibration principles. Many resources detail optimized design criteria for piezoelectric accelerometers, providing a rigorous design experience.

For example, when discussing the resonant frequency of a comb drive, Kaajakari doesn't just give you the formula; he shows you how changing the finger overlap or the gap spacing affects your actuation voltage and shock tolerance.
The Book’s Fix: Chapter 5 explains the “release” process. If you don’t use supercritical CO2 drying or anti-stiction coatings (like self-assembled monolayers), your beams will stick to the substrate. Kaajakari provides the Hamaker constant calculations to predict if van der Waals forces will pull your beam down permanently. practical mems ville kaajakari pdf work
