Special Issue Information

Dear Colleagues,

Having emerged over 40 years ago as a smart servo and control system, piezoelectric actuators and motors have been applied in many industry fields, such as aerospace, weapons, optical instruments, biomedical equipment, etc. Their advantages, including a simple configuration, being lightweight, high-precision positioning, no electromagnetic interference, self-locking when powered off, and a fast response, highlight the benefits of piezoelectric actuators and motors, promoting their industrial applications. Over the past 10 years, a series of novel piezoelectric actuators and motors with new structures and principles has been successively developed, greatly and significantly facilitating the progress of piezoelectric actuation technology. To further advance piezoelectric actuation technology and its applications in high-end equipment, this Special Issue seeks to showcase research papers, communications, and review articles focusing on recent advances of piezoelectric actuators and motors, including their design, modeling, simulation, experiments, and applications.

We look forward to receiving your submissions!

The paper represents both numerical simulations and experimental investigations of a piezoelectric active preload system that is foreseen to be applied to the active preload control system of rotors of ultrasonic piezoelectric motors. The investigated preload system is based on the piezoelectric multilayer actuator and disc-shaped spring, which is attached at end of the actuator. The total volume and mass of the preload system are 275 mm3 and 4.3 g, respectively. The results of investigations demonstrate strong agreement between the experimental and simulation data, showing nearly linear displacement and output force responses within an input voltage range of 20 V to 75 V in the frequency range from DC to 200 Hz. In the investigated ranges, the active preload system is able to ensure up to 1 N force with displacement amplitude up to 30 µm, which were obtained at a driving signal of 75 V. These results show that the investigated active preload system can replace passive preload devices in ultrasonic piezoelectric motors which are subjected to strict requirements in terms of their mass and mounting volume.

Recent research has focused on energy recovery and storage technologies. One of the materials allowing the recovery of dissipated energy is the piezoelectric material (PE). These functional materials perform reversible energy conversion, transforming electrical energy into mechanical and vice versa. In this study, we investigate the recovery of vibratory energy in vehicle suspension systems—energy traditionally dissipated by conventional shock absorbers—using piezoelectric materials to capture this wasted energy and redirect it to the vehicle’s auxiliary power supply network. We propose an integrated electromechanical model incorporating piezoelectric actuators in parallel with the suspension mechanism. The collected energy is processed and stored for later use in powering accessories such as windows and mirrors. The idea is to integrate renewable energy sources to optimize the performance of the vehicle. We proposed a Multiphysics model of the system under a software used to this type of modeling (Simcenter AMESim v1610_student). The simulation results of the system and its various sub-systems are presented for studying the piezo-actuator response to reduce consumption and increase energy performance in a vehicle. These findings will undergo experimental validation in the project’s subsequent phase. Full article

The bandwidth and output power of underwater acoustic transmitters are important for high-performance sonar detection systems.

The bandwidth and output power of underwater acoustic transmitters are important for high-performance sonar detection systems. A mismatch between the impedance of the transducer and the transmitting circuit results in a low power factor, significantly limiting the sonar’s operating bandwidth and detection range. In addition, the radial head structure of the Tonpilz transducer plays an important role in determining the radiation characteristics of the sound field. This paper proposes a new radiation head structure along with an impedance-matching network circuit. First, a mathematical model of active power is established based on the Krimholtz–Leedom–Matthaei (KLM) model of the transducer. The adaptive Gauss–Newton algorithm is then used to calculate the parameters of the broadband impedance-matching network components, ultimately determining the network parameters and the structure of the transducer’s radiation head. Experimental results indicate that the transmitter voltage response of the proposed transducer is 6 dB higher than that of a conventional transducer and can be further increased by 5 dB with impedance matching. The impedance-matching network enhances the power factor of the transducer by 3.2 times, expands the frequency band by a factor of 1.6, and significantly enhances the acoustic field radiation characteristics of the underwater acoustic transducer.
