Description
Summary:In this article, a novel flexure-based 3-degree-of-freedom elliptical micro/nano-positioning motion stage was developed to obtain translation motions along the x, y, and z directions with high working bandwidth. The stage was configurations with a XYZ vertical motion to ensure the crosstalk between each axis is small enough. The motion stage was driven by three piezoelectric actuators. The corresponding working principles and stiffness modeling were detailed in this article. In addition, experimental testing was conducted to investigate the performances of the motion stage. The obtained strokes in x, y, and z directions are 10.39, 15.43, and 15.55 μm, respectively. The response rise time for each axis is within 10 ms, and the maximum crosstalk all within 1.2% ensured the rapid tracking can be achieved.
