Abstract
We study the existence and stability of periodic solutions of a canonical
mass-spring model of electrostatically actuated micro-electro-mechanical
system (MEMS) by means of classical topological techniques like a-priori
bounds, Leray-Schauder degree and topological index. A saddle-node bi-
furcation is revealed, in analogy with the autonomous case.
1 Introduction.
The purpose of this paper is to study analytically the existence and stability of
periodic solutions of an idealized mass-spring model of electrostatically actuated
micro-electro-mechanical system (MEMS) which has become canonical in the
