Micro- and nanoelectromechanical systems (MEMS and NEMS), which
combine electronics with miniature-size mechanical devices, are
essential components of modern technology. It is the mathematical
model describing “electrostatically actuated” MEMS that is
addressed in this monograph. Even the simplified models that the
authors deal with still lead to very interesting second- and
fourth-order nonlinear elliptic equations (in the stationary case) and
to nonlinear parabolic equations (in the dynamic case). While
nonlinear eigenvalue problems—where the stationary MEMS models
fit—are a well-developed field of PDEs, the type of inverse
square nonlinearity that appears here helps shed a new light on the
class of singular supercritical problems and their specific
challenges.

Besides the practical considerations, the model is a rich source of
interesting mathematical phenomena. Numerics, formal asymptotic analysis,
and ODE methods give lots of information and point to many conjectures.
However, even in the simplest idealized versions of electrostatic MEMS,
one essentially needs the full available arsenal of modern PDE techniques
to do the required rigorous mathematical analysis, which is the main
objective of this volume. This monograph could therefore be used as an
advanced graduate text for a motivational introduction to many recent
methods of nonlinear analysis and PDEs through the analysis of a set of
equations that have enormous practical significance.
