Self-healing materials research spans many academic disciplines and employs a wide range of methodologies. Some of the developed concepts are driven by the direct application of the materials. However, a deeper understanding of the basic mechanisms and principles of self-healing materials is still a challenging aim. Nature has mostly served as an inspiration for the development of new self-healing materials, and it will undoubtedly continue to be a significant source of inspiration for the creation of novel ideas. This review encompasses the principles of self-healing mechanisms based on the concepts of autonomous and non-autonomous procedures. Studies based on smart composite materials with autonomous self-healing properties are also included and discussed from two aspects of intrinsic or extrinsic abilities, taking into consideration their components and structures as well as the design of these composites. Finally, special attention is given to the application of the materials in several fields such as aerospace, automotive, marine, energy, medical and healthcare, military, and construction.

“…These materials can potentially deal with the considerably enhanced performance of ultrasonic transducers through a large bandwidth and high sensitivity for both transmission and reception configurations [ 5 ]. Ceramic PZT transducers are used for energy harvesting [ 6 ], structural health monitoring [ 7 ], damage detection in concrete for constructional applications [ 8 ], and ultrasonic diagnostic techniques in medical applications [ 9 ]. Recently, single crystal PMN-PT material-based transducers have received the most attention owing to their high attenuation, and enhanced bandwidth is used in many applications, such as underwater acoustics [ 10 ], biomedical applications, and energy harvesting [ 11 ].…”

Multilayer piezocomposite transducers are widely used in many applications where broad bandwidth is required for tracking and detection purposes. However, it is difficult to operate these multilayer transducers efficiently under frequencies of 100 kHz. Therefore, this work presents the modeling and optimization of a five-layer piezocomposite transducer with ten variables of nonuniform layer thicknesses and different volume fractions by exploiting the strength of the genetic algorithm (GA) with a one-dimensional model (ODM). The ODM executes matrix manipulation by resolving wave equations and produces mechanical output in the form of pressure and electrical impedance. The product of gain and bandwidth is the required function to be maximized in this multi-objective and multivariate optimization problem, which is a challenging task having ten variables. Converting it into the minimization problem, the reciprocal of the gain-bandwidth product is considered. The total thickness is adjusted to keep the central frequency at approximately 50–60 kHz. Piezocomposite transducers with three active materials, PZT5h, PZT4d, PMN-PT, and CY1301 polymer, as passive materials were designed, simulated, and statistically evaluated. The results show significant improvement in gain bandwidth compared to previous existing techniques.

Strengthening and repairing infrastructure with fiber‐reinforced polymers while achieving low‐cost, real‐time monitoring of cracks in engineering structures is highly challenging. Here, a piezoelectric glass‐fiber‐reinforced polymer (piezo‐GFRP) sensor was used to monitor the mechanical behavior of cement beams with cracks under cyclic bending. The output voltage and frequency of the sensor were shown to be effective feedback signals for determining the mechanical behavior. The thin piezo‐GFRP sensor showed sufficient piezoelectric sensitivity to monitor the slight variations in the mechanical behavior of the cement beams during the early stages of cracking. This result indicates that such sensors have the potential for the multi‐functional structural health monitoring of engineering structures.This article is protected by copyright.
