A novel multi-degree-of-freedom (MDOF) motion platform was developed using symmetric piezoelectric plate and a Ni alloy micro-pusher element. An additive manufacturing (AM) technique was employed to manufacture a Ni alloy micro-pusher, which was then attached at the midpoint of the long side of a piezoelectric plate with dual electrodes to construct a symmetric piezoelectric actuator (SPA). The research integrated the concept of bricks, and three different vibration modes of the SPA were designed to develop a MDOF motion platform, which was able to rotate a hemisphere device along three perpendicular axes. The experiment demonstrated the MDOF motion platform working frequencies along the X, Y, and Z axes to be 223. 6, 223. 2, and 225 kHz and the rotation speeds to reach 76 rpm, 71 rpm, and 192 rpm, respectively, at a driving voltage of 30Vpp. In the future, this MDOF motion platform may be used for a number of applications, such as portable mobile devices and sun-tracking systems in green energy harvesters.
