Modal interactions of flexural and torsional vibrations in a microcantilever
H. J. R. Westra, H. S. J. van der Zant, W. J. Venstra
The nonlinear interactions between flexural and torsional modes of a microcantilever are experimentally studied. The coupling is demonstrated by measuring the frequency response of…
Interactions between directly and parametrically driven vibration modes in a micromechanical resonator
H. J. R. Westra, D. M. Karabacak, S. H. Brongersma +3
The interactions between parametrically and directly driven vibration modes of a clamped-clamped beam resonator are studied. An integrated piezoelectric transducer is used for dire…
Q-factor control of a microcantilever by mechanical sideband excitation
W. J. Venstra, H. J. R. Westra, H. S. J. van der Zant
We demonstrate the coupling between the fundamental and second flexural mode of a microcantilever. A mechanical analogue of cavity-optomechanics is then employed, where the mechani…
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…
