The piezoelectric actuators with local ring electrodes were fabricated by screen electrode printing, and its driving force was tested and studied. A clamping force test platform was built to test and analyze the radial clamping force of the piezoelectric actuators with local ring electrodes and the conventional electrode piezoelectric actuator. The experimental results show that under the excitation of square wave and sine wave with a frequency of 0.2 Hz and a peak value of 200 V, the peak values of radial clamping force in the electrode region of piezoelectric actuators with local ring electrodes are 0.60 N and 0.58 N, respectively. And the peak responses of the two clamping forces are 2.72 and 2.76 times higher than those of the conventional electrode piezoelectric actuator respectively. The peak values of the reverse clamping force in the electrodeless area are 0.29 N and 0.28 N, which are slightly larger than those of the conventional piezoelectric actuators. The experimental results also verify the orthogonality of the piezoelectric actuators with local ring electrodes.
