Temperature dependence of the near-wall oscillation of microcantilevers submerged in liquid environment (original) (raw)

Applied Physics Letters, 2007

Abstract

This letter presents theoretical and experimental investigations of the temperature effects (30-70 °C) on the frequency responses of three different microcantilevers [thickness (h)/length (L)2=34.7,141,275 m-1] near a solid surface in aqueous liquid. The peak resonance response frequency shifts in the near-wall region are dominated by the temperature effects associated with the pronounced viscous dissipative effect of liquid. A relatively short and thick cantilever with a large value of h/L2 demonstrates higher thermal sensitivity Deltaf/DeltaT in the near-wall region.
