Anomalous Thermomechanical Softening-Hardening Transitions in Micro-oscillators

Sahai T., Bhiladvala R., Zehnder A., Cornell University, US

This work documents and explains a counter-intuitive nonlinear phenomenon, where the laser-detected resonant motion of forced, micromechanical oscillators can be tuned from softening to hardening by increasing the laser power incident on a prestressed silicon [...]

Modeling and Dynamics of Coupled Dome-shaped Micromechanical Oscillators

Sahai T., Zehnder A.T., Cornell University, US

In this work we analyze a feasible approach for constructing coupled micromechanical oscillators that synchronize. For this purpose we use dome shaped micro-oscillators that have previously been used to build radios. These oscillators are fabricated [...]
