Due to the ir small size and low damping\, these devices often exhibit significant no nlinearity\, which narrows the operational range of these impressive appli cations. Therefore\, understanding the mechanisms leading to nonlinearity in such systems is crucial for eliminating obstacles to their further deve lopment. Motivated by the need to advance current capabilities of Micro-El ectro-Mechanical Systems (MEMS)\, our research has been focused on the imp lementation of intentional intrinsic nonlinearity in the design of micro r esonators. We have demonstrated that harnessing nonlinearity enables the e xploitation of various nonlinear phenomena\, not attainable in linear sett ings\, such as broadband resonances\, dynamic instabilities\, nonlinear hy steresis\, and\npassive targeted energy transfers.\n\nWe have developed a comprehensive analytical\, numerical\, and experimental methodology to con sider structural nonlinearity as a main design factor\, enabling to tailor mechanical resonances and achieve targeted performance. We investigated t he mechanism of geometric nonlinearity in a non-prismatic microresonator a nd suggested strategies to tailor the various types of nonlinear resonance . Our more recent works focus on exploiting nonlinearity and multimodality simultaneously by internally coupling two or more modes through the mecha nism of internal resonance. This talk will introduce various types of nonl inear phenomena realized in micro systems and discuss their unique behavio ral features that can be exploited in the field of MEMS.\n\nSpeaker(s): Dr .
