Dynamic Behaviors of Controllably Buckled Thin Films

The controlled buckling of thin films is essential in the stretchable and curvilinear electronics.  Through the rigorous governing equations accounting for geometric nonlinearity, dynamic behaviors of buckled thin films, which serve as interconnects in curvilinear electronics, are investigated in detail.  The surface effects from surface elasticity and residual surface stress are taken into account due to the thin films thickness at small scale, and the effects of surface properties on dynamic behaviors are obtained.  The results will guide the design of interconnects to avoid resonance in complicated noise environment.
