研制了一种利用压电剪切应变产生角位移的扭转驱动器。致动器是由沿长度方向沿着极化的偶数个节段组成的管，这些节段被粘合在一起，并且接头充当电极以施加驱动电压。在原型致动器上测量的实验数据：（i）证明了所提出的扭转致动器的概念，（ii）表明致动器在扭矩Lend下良好地起作用，以及（iii）表明与先前报道的扭转致动器设计相比，它具有上级特性。(C)1998年美国物理学会。[S0003-6951（98）02620-5]。
A torsional actuator generating angular displacement from piezoelectric shear strain was developed. The actuator is a tube consisting of an even number of segments poled along the length, which are adhesively bonded together, and the joints act as electrodes to apply the driving voltage. The experimental data measured on the prototype actuator: (i) prove the proposed concept of the torsional actuator, (ii) show that the actuator functions well under the torque lend, and (iii) demonstrate that it has superior characteristics compared to previously reported designs of torsional actuators.
