提出了一种新型压电步进电机，具有结构紧凑、刚性好、结构简单、可任意方向操作等特点。虽然在室温下进行了测试，但由于其操作条件宽松且步长较大，因此被认为可以在低温下工作。该电机由压电扫描管实现，该压电扫描管被轴向切割成几乎两半，并且通过轴的弹簧部分在两端处夹持中空轴。使压电管的两个半体在一个方向上单独变形并同时恢复的两个驱动电压将使轴在相反方向上移动，反之亦然。
We present a novel piezoelectric stepper motor featuring high compactness, rigidity, simplicity, and any direction operability. Although tested in room temperature, it is believed to work in low temperatures, owing to its loose operation conditions and large step size. The motor is implemented with a piezoelectric scanner tube that is axially cut into almost two halves and clamp holds a hollow shaft inside at both ends via the spring parts of the shaft. Two driving voltages that singly deform the two halves of the piezotube in one direction and recover simultaneously will move the shaft in the opposite direction, and vice versa.
