Advantageous Utilization of Nonlinear Phenomena in Micro-Structures and Macro-Structures: Applications to Micro-Resonators and Atomic Force Microscopy

Within this work, the nonlinear oscillations of various beam-like structures are studied. Methods are developed to analyze systems of this type to better understand their behavior in order to utilize the nonlinear phenomena associated with them and to provide insights for device development. The specific applications explored within this study are piezoelectric micro-scale resonators, micro-resonator arrays, the cantilever probes of atomic force microscopes, and a macro-scale test apparatus for the AFM probe. In order to analytically, numerically, and experimentally study these systems, various methods are employed. Analytical models are developed…
