Abstract：In order to obtain the relationship between the changes of resonance frequency of microcantilever with double beams and the dimensions of added mass, the formula of resonance frequency of microcantilever with double beams was deduced.In addition, using the samples of nine kinds of microcantilevers with double beams, the relationship between the lengths of added mass and the resonance frequencies was analyzed.The results show that the resonance frequency of microcantilever decreases with the increasing length of added mass.Moreover, when the ratio of the length of added mass versus the total length of microcantilever increases, the ratio of the in-duced resonance frequency by added mass versus the resonance frequency of microcantilever decreases.
