The book is structured with a "tutorial approach," containing over that guide readers through various aspects of MEMS design. Its primary aim is to teach how to design a microdevice to meet specific target specifications, making it a "perfect companion" to fabrication-heavy texts. Key themes include:

To demonstrate the utility of this work, consider the practical steps to design a standard comb-drive capacitive accelerometer using Kaajakari’s methodology:

Micro-Electro-Mechanical Systems (MEMS) are the unsung heroes of modern technology. They are the tiny accelerometers that trigger your smartphone’s screen rotation, the gyroscopes that stabilize your drone, and the micro-mirrors that power cinema projectors. Yet, for many engineers and students, diving into MEMS design feels like entering a forbidden labyrinth. The physics is complex (involving solid mechanics, fluid dynamics, and electrostatics), the fabrication is expensive, and the textbooks are often dense with theory but light on application .
For a MEMS accelerometer, the total noise determines minimum detectable signal. Kaajakari shows that designing for high ( Q ) (low damping) in vacuum reduces thermomechanical noise but increases ringing time—a trade-off. They are the tiny accelerometers that trigger your
The PDF work here is crucial: residual stress. Kaajakari provides practical formulas to calculate the deflection of clamped-clamped beams due to compressive stress.
