A piezoelectric motorization system has a mechanically flexible body that has one or more surfaces for placing piezoelectric actuators. The system has groups of piezoelectric actuators each positioned on one of the surfaces of the mechanically flexible body that is connected to the electronic circuitry. The electronic circuitry controls the driving of the mechanical loads by the mechanically flexible body by injecting sets of control signals into different groups of actuators positioned on the mechanically flexible body. Each control signal operates groups of driving frequencies with an adjustable amplitude ratio and an adjustable phase difference among driving frequencies. And, under a set of boundary conditions exhibited by a set of structural dimensions of the mechanically flexible body, each control signal induces multi-mode resonance of the mechanically flexible body for driving the mechanical loads multi-dimensionally.
