Parametric Resonance in Microcantilevers with Application in Mass Sensing

1.1 Characteristic phase dependance between direct forcing and parametric amplified forcing phase. Plotted is gain vs. phase at resonance for a 2.1 Simulated response of a parametrically resonant system under two driving conditions. The drive signal is shifted by pi-radians. The physical response, displacement is plotted here, is identical as driven by the two signals. Thus, phase shifting the ...

Sensing surface PEGylation with microcantilevers

Polymers are often used to modify surface properties to control interfacial processes. Their sensitivity to solvent conditions and ability to undergo conformational transitions makes polymers attractive in tailoring surface properties with specific functionalities leading to applications in diverse areas ranging from tribology to colloidal stability and medicine. A key example is polyethylene g...

Resonating modes of vibrating microcantilevers in liquid

A study of nanomechanical cantilevers vibrating at various resonating modes in liquid is presented. Resonant frequency spectrum with 16 well resolved flexural modes is obtained. The quality factor increased from 1 at mode 1 to 30 at mode 16. The theoretical estimate of eigenfrequency using the Elmer–Dreier model F.-J. Elmer and M. Dreier, J. Appl. Phys. 81, 12 1997 and Sader’s extended viscous ...
