Special Issue Information

Dear Colleagues,

Piezoelectric actuators are often used in precision positioning devices because of their nanometer-order resolution. In addition, they are small and light and generate a large blocking force. On the other hand, the deformation of piezoelectric actuators is generally limited to several tens of micrometers. In order to overcome this disadvantage, they are often combined with mechanisms to enlarge their movable range by accumulating minute motions. Since hysteresis and creep also deteriorate the performance of the piezoelectric actuators, the displacement, supplied electric charge or driving current is fed back for closed-loop or sensorless control methods. Some models that compensate for the hysteresis also have been studied. Smart structures with collocated piezoelectric composite can suppress vibration. These developments expand and enhance their applications to science, technology, precision engineering, and industry such as material science, space science, nanotechnology, biotechnology, precision machining, and semiconductor production. This Special Issue will collect contributions related (but not limited) to the following topics: Design of piezoelectric positioners, movers, and motors; driver for piezoelectric actuators; control strategy of piezoelectric actuators; modeling/simulation of piezoelectric actuators; piezoelectric energy harvesting; piezoelectric transducers; piezoelectric composites and smart structures; piezoelectric and structural health monitoring; near-field ultrasonic levitation; and applications to science, technology, precision engineering, and industry.

Piezoelectric unimorph deformable mirrors offer a cheap solution to adaptive optics, with mass production capability. However, standard solutions have significant drawbacks: (i) the static shape is sensitive to the temperature, and (ii) the low structural damping limits the control bandwidth, because of the interaction between the shape control and the vibration modes of the mirror. This paper discusses how these two problems may be alleviated by using a mirror covered with an array of actuators working in d31 mode on the back side and a ring of transducers (actuators and sensors) on the front side, outside the pupil of the mirror.

A major inhibition to the widespread use of laminate structures is the inability of nondestructive testing techniques to effectively evaluate the bondline integrity. This work proposes and analyzes a bondline-integrity health monitoring approach utilizing shear-mode (d15) piezoelectric transducers. The d15 transducers were embedded in the bondlines of symmetric laminate structures to monitor and evaluate the bondline integrity using ultrasonic inspection. The d15 piezoelectric transducers made of lead zirconate titanate (PZT) enabled ultrasonic inspection of bonds by actuating and sensing antisymmetric waves in laminate structures. Design considerations, fabrication process, and experimental methods for testing a laminate specimen are presented. Designs included bondline-embedded d15 PZT piezoelectric transducers with surface-mounted transverse (d31) piezoelectric transducers for signal comparison. Defects in the bondline were created by a quasi-static three-point bending test, with results showing the ability of d15 piezoelectric transducers to detect bondline damage. Two damage indices based on Pearson correlation coefficient and normalized signal energy were implemented to evaluate the presence of damage and its severity. The experimental results demonstrate the ability of bondline-embedded d15 piezoelectric transducers to be used as actuators and sensors for ultrasonic health monitoring of bondline integrity. A comparison between surface-mounted d31 PZT and bondline-embedded d15 PZT sensors was also conducted. It was seen that signals sensed by bondline-embedded d15 PZTs showed higher distortion due to bondline defects compared with the sensed signals from the surface-mounted d31 PZT. Full article
