Piezoelectric materials are widely used in electromechanical coupling components including actuators, kinetic sensors, and transducers, as well as in kinetic energy harvesters that convert mechanical energy into electricity and thus can power wireless sensing networks and the Internet of Things (IoT). Because the number of deployed energy harvesting powered systems is projected to explode, the supply of piezoelectric energy harvesters is also expected to be boosted. However, despite being able to produce green electricity from the ambient environment, high‐performance piezoelectrics (i.e., piezoelectric ceramics) are energy intensive in research and manufacturing. For instance, the design of new piezoceramics relies on experimental trials, which need high process temperatures and thus cause high consumption and waste of energy. Also, the dominant element in high‐performance piezoceramics is hazardous Pb, but substituting Pb with other nonhazardous elements may lead to a compromise of performance, extending the energy payback time and imposing a question of trade‐offs between energy and environmental benefits. Meanwhile, piezoceramics are not well recycled, raising even more issues in terms of energy saving and environmental protection. This paper discusses these issues and then proposes solutions and provides perspectives to the future development of different aspects of piezoceramic research and industry.

“…The inchworm drive motors are modeled by the unique crawling principle of the insect inchworm, and are driven by the alternating mode of "Clamping-Drive-Clamping", which has a large driving force and a large stroke, but they also have a large volume, complex structure, and slow movement speed [1][2]. Ultrasonic drive motors are driven by elliptical friction under the action of applied ultrasonic voltage, with fast speed and self-locking characteristics of power failure, but they have high requirements for the drive signal and serious heating problems caused by friction and wear [3][4]. The stick-slip drive motors adopt an asymmetric drive wave (sawtooth wave signal), and utilize the difference between the maximum static friction and sliding friction to drive by inertia, with a simple principle of motion, compact structure, and a motion speed between the inchworm motors and ultrasonic motors [5][6][7][8].…”

In the article, the design of a piezoelectric stick-slip rotary motor is proposed that can be used as the rotary drive part of a micro-nano operation. First, a force-coupled stator based on a flexible mechanism with a diameter of 23 mm was designed. Based on the designed stator, the structure of the rotary motor is constructed and its motion steps are analyzed. Then, finite element analysis is performed. Finally, the performance of the motor is tested and conclusions are drawn. The simulation and experimental results show that the developed motor performs well.
