Mechanical stiffening, bistability, and bit operations in a microcantilever
Warner J. Venstra, Hidde J. R. Westra, Herre S. J. van der Zant
We investigate the nonlinear dynamics of microcantilevers. We demonstrate mechanical stiffening of the frequency response at large amplitudes, originating from the geometric nonlin…
Nonlinear modal interactions in clamped-clamped mechanical resonators
H. J. R. Westra, M. Poot, H. S. J. van der Zant +1
A theoretical and experimental investigation is presented on the intermodal coupling between the flexural vibration modes of a single clamped-clamped beam. Nonlinear coupling allow…
Magnetomotive drive and detection of clamped-clamped mechanical resonators in water
W. J. Venstra, H. J. R. Westra, K. Babaei Gavan +1
We demonstrate magnetomotive drive and detection of doubly clamped string resonators in water. A compact 1.9 T permanent magnet is used to detect the fundamental and higher flexura…
