Cantilever sensors have attracted much attention due to their potential as a platform for the development of many physics, chemical, and biological sensors. An analytical model based on analyzing the equivalent circuit of a piezoelectric cantilever as a rheological sensor has been derived and applied in real test. This model can be used to significantly improve the resolution and detection range of the devices. Based on this model, piezoelectric cantilevers have been used for characterizing Newtonian oils with viscosity between 1 and 104mPa s, and good agreements between experimental and modeled results have been obtained.
