• [7][8][9]. The higher-order eigenmodes of the cantilever can effectively improve Q-factor, imaging rate, and mass sensing resolution [10][11]. For traditional rectangular cantilevers, the higher-order modal response is usually weaker than that of the fundamental mode in ambient air [12]. This

• applications that range from mass-sensing [20] to nanometrology of thin films and embedded nanostructures. These applications are based on elastic multi-mode excitations that last few oscillations [21]. In this context the present analysis will enlarge the space of parameters to be exploited for the sensing
