Substantial improvement of rotation driving accuracy is urgently needed and facing challenges. Miniature bidirectional rotary actuators with high-precision and controllable fallback rate require novel driving principles. Here, on the basis of a proposed biomimetic stick–slip motion principle, a novel piezoelectric-thermal coupling bidirectional rotary actuator was developed. The integrated mantis grasping leglike biomimetic claws and heating rods could realize the clockwise macroscopic rotation and anticlockwise macroscopic fallback of a cylindrical rotator, generated by piezoelectric stick–slip and thermal expansion, respectively. The rotation fallback was effectively inhibited at relatively lower frequencies and higher voltages, as a slight fallback rate of 0.095 was confirmed in term of 0.5 Hz and 80 V. An extraordinary piezoelectric-driven macroscopic rotation resolution of 0.2 μrad and thermal-induced microscopic resolution of 0.00073°/°C were experimentally revealed with the aid of real-time observation of the clockwise slow sticking and anticlockwise instantaneous slipping processes by using three-dimensional optical imaging.

Novel crystallization behaviors of Zr 55 Cu 30 Al 10 Ni 5 bulk metallic glass are investigated. On the one hand, mixed oxides, including CuO, CuAlO 2 , CuAl 2 O 4 and ZrO 2 , show sequential oxidation process determined by coupling effects of specific cyclic load and temperature. On the other hand, at a temperature (100 °C) by far lower than T g of 412 °C, under cyclic loading condition, non-oxidized binary alloy CuZr 2 is precipitated; the thermo-mechanical coupled effects of temperature below T g and fatigue accumulation on the non-oxidized crystallization behaviors are revealed. Meanwhile, at a constant temperature of 400 °C, by comparing among the XRD patterns, respectively, obtained from tensile, creep and fatigue fractures, the dominating effect of cyclic load on the generation of non-oxidized CuZr 2 is verified. Furthermore, the crystallization behavior of amorphous phases under cyclic loading condition is observed through TEM micrograph and diffraction pattern at 100 °C.
