Abstract
In this paper authors present two methods of determining the cantilever displacement sensitivity. In both cases the cantilevers are examined in dynamic condition for cantilever vibrating with frequency range close to resonance frequency. One of the method uses as measurement tool a white light interferometer, the another one uses the laser interferometric vibrometer. For adequate comparing methods, obtained results refer to the same cantilever with piezoresistive Wheatstone bridge. In this paper authors also present the fabrication process of piezoresistive cantilevers with planar tip adapted for working in a shear force [1]. Additionally the piezoresistive circuit characterization by impedance spectroscopy is presented. Finally the spring constant is determined basing on frequency response of the cantilever measured from thermal noise density [2]. Basing on obtained results authors made a conclusion that both methods can be successfully used for accurate characterization piazoresistive cantilevers work in a non-contact resonance mode.
