“…• Non-metallic materials: many scholars have used the IRT to measure the thermal behaviors of the nonmetallic materials during the fatigue process, e.g., Barati et al 119 As such, scholars should not restrict themselves to predicting fatigue life alone but rather should broaden the scope of their research and explore the potential applications of heat generation to the fullest extent possible. Moreover, it is crucial that the theoretical mechanism of thermo-based fatigue life models developed on tested specimens should be extended for use on actual components in the future.…”

“…In particular, the thermo‐based models for predicting fatigue life have many potential areas for further exploration. From my perspective, the main areas of focus for future research include: Non‐metallic materials : many scholars have used the IRT to measure the thermal behaviors of the non‐metallic materials during the fatigue process, e.g., Barati et al 119 applied the IRT to a soft lead zirconate titanate (PZT) ferroelectric ceramic; Li et al 120 to a short carbon fiber reinforced polyether‐ether‐ketone; Le Saux et al 121 and Masquelier et al 122 to the rubber‐like materials. The related methodologies reviewed in section 2 are worth attempting to apply to these materials. Multi‐environmental fatigue tests : Chhith et al 123 employed IRT in fretting fatigue studies, while Wu et al 124 applied it to corrosion fatigue investigations.…”

The main objective of this review paper is twofold: Recall the most captivating areas of research in predicting the fatigue life of metals with the application of thermal methodology, particularly for the stress‐controlled fatigue tests. The explicit lifetime models reviewed have been developed by scholars over the past two decades owing to the advancements in infrared thermal imaging technology. Introduce, discuss, and conclude a broad range of alternative theoretical frameworks in thermodynamics. Some investigations are made with the previous methods, including the most recent evolutions of lifetime models for structural integrity across various fields. Some future perspectives are provided in final, which could pave the way for a new realistic or potential capability.

Within the optimization process, the intensity of the electric field will be identified explicitly for each of the eight points.…”

A new ferroelectric energy harvesting concept is investigated theoretically, based on a thermo-electromechanical multiscale constitutive framework in connection with the so-called condensed method. Taking advantage of comparatively large changes of strain and polarization due to domain switching, the electric output is higher compared to what is commonly known as piezoelectric energy harvesting. Dissipative self-heating and augmented damage accumulation, on the other hand, may impede the operability of the harvesting device, in particular if tensile stress is required for depolarization, as suggested by recent works. The new harvesting cycle thus dispenses with tensile stresses and instead exploits the potential of existing residual stresses. It is further investigated to which extent a bias field, commonly applied to support repolarization as an important stage of the cycle, can be omitted, saving considerable effort on the technical implementation. Process parameters are obtained from various simulations by pareto-ptimization, considering, inter alia, the effect of ambient temperature.

“…In the high-frequency ultrasound operation mode, over-coercive voltage driving can cause self-heating problems associated with electrical losses of the ferroelectrics 38,39 . Moreover, repetitive switching polarization during excitation can induce dielectric losses, which are derived from the domain wall moving 40 .…”

Dual-frequency ultrasound has advantages over conventional ultrasound, which operates at a specific frequency band, due to its additional frequency response. Moreover, a tunable frequency from a single transducer enables sonographers to achieve ultrasound images with a large detection area and high resolution. This facilitates the availability of more advanced techniques that require low- and high frequency ultrasound simultaneously such as harmonic imaging and image-guided therapy. In this article, we present a novel method for dual-frequency ultrasound generation from a ferroelectric piezoelectric micromachined ultrasound transducer (PMUT). Uniformly designed transducer arrays can be used for both deep low-resolution imaging and shallow high-resolution imaging. To switch the ultrasound frequency, the only requirement is to tune a DC bias for controlling the polarization state of the ferroelectric film. Flextensional vibration of the PMUT’s membrane strongly depends on the polarization state, producing low- and high-frequency ultrasound from a single excitation frequency. This strategy for dual-frequency ultrasound dispenses with the requirement for either multi-electrode configurations or hetero-designed elements, which are integrated into an array. Consequently, this technique significantly reduces the design complexity of transducer arrays and their associated driving circuits.
