“…As mechanical energy harvesting-based devices, TENGs must frequently suffer from various mechanical impacts. Such interaction inevitably accelerates devices fracture, leading to degradation in durability and lifespan of the device. − The combination of self-healing polymers with TENGs is a straightforward method to overcome the above challenges in TENGs. − The self-healing polymer is one type of smart material allowing fractures to restore to their original state. , The acquisition of this healability is attributed to the existence of some special bonds, including dynamic covalent bonds, reversible covalent bonds, and noncovalent bonds in the molecular structures of self-healing polymers. , From a molecular level (Figure (a)), mechanical damage may cause polymer chain cleavage, and further generate some reactive end-groups. Compared to traditional polymers, the reactive end-groups generated in self-healing polymers possess the special ability to reassemble at the broken site, leading to the reformation of broken chemical bonds.…”

Serious climate changes and energy-related environmental problems are currently critical issues in the world. In order to reduce carbon emissions and save our environment, renewable energy harvesting technologies will serve as a key solution in the near future. Among them, triboelectric nanogenerators (TENGs), which is one of the most promising mechanical energy harvesters by means of contact electrification phenomenon, are explosively developing due to abundant wasting mechanical energy sources and a number of superior advantages in a wide availability and selection of materials, relatively simple device configurations, and low-cost processing. Significant experimental and theoretical efforts have been achieved toward understanding fundamental behaviors and a wide range of demonstrations since its report in 2012. As a result, considerable technological advancement has been exhibited and it advances the timeline of achievement in the proposed roadmap. Now, the technology has reached the stage of prototype development with verification of performance beyond the lab scale environment toward its commercialization. In this review, distinguished authors in the world worked together to summarize the state of the art in theory, materials, devices, systems, circuits, and applications in TENG fields. The great research achievements of researchers in this field around the world over the past decade are expected to play a major role in coming to fruition of unexpectedly accelerated technological advances over the next decade.

“…In SMASH systems, physical and chemical healing are synergistically combined to enable the host polymer with the intrinsic capability of healing macroscopic cracks on a molecular scale. 86 In short, the shape-memory properties are manipulated to physically close the crack that is chemically healed. Although the need for thermo or light activation to trigger the healing still poses an obstacle to autonomic repairability in dental polymers, SMASH technology is an interesting approach and may be tuned to allow for clinical translation.…”

The rapid development of the aviation industry has put forward higher and higher requirements for material properties, and the research on smart material structure has also received widespread attention. Smart materials (e.g., piezoelectric materials, shape memory materials, and giant magnetostrictive materials) have unique physical properties and excellent integration properties, and they perform well as sensors or actuators in the aviation industry, providing a solid material foundation for various intelligent applications in the aviation industry. As a popular smart material, piezoelectric materials have a large number of application research in structural health monitoring, energy harvest, vibration and noise control, damage control, and other fields. As a unique material with deformation ability, shape memory materials have their own outstanding performance in the field of shape control, low-shock release, vibration control, and impact absorption. At the same time, as a material to assist other structures, it also has important applications in the fields of sealing connection and structural self-healing. Giant magnetostrictive material is a representative advanced material, which has unique application advantages in guided wave monitoring, vibration control, energy harvest, and other directions. In addition, giant magnetostrictive materials themselves have high-resolution output, and there are many studies in the direction of high-precision actuators. Some smart materials are summarized and discussed in the above application directions, aiming at providing a reference for the initial development of follow-up related research.
