  • Publication number: 20190372483
    Abstract: A piezoelectric motorization system for driving mechanical loads multi-dimensionally by an electronic circuitry is disclosed. The piezoelectric motorization system has a piezoelectric apparatus that is constructed by a mechanically flexible body that has multiple piezoelectric actuators attached its surfaces, where these actuators are controlled by an electronic circuitry. The mechanically flexible body has a finite structure with a sets of boundary conditions to determine its out-of-plane resonant modes. The electronic circuitry inject at least two sets of control signals into different groups of actuators at or near different resonant frequencies. Using these control signals, traveling waves can be generated on the piezoelectric apparatus to move mechanical loads placed on its surface. Or, the traveling waves are used to propel the piezoelectric apparatus for motorization.
