“…[32] Moreover, in addition to human motion detection [113] and electric generator, [114] self-healing soft electronics are expected to be combined with artificial intelligence (AI) analysis systems for environmental sensing (Figure 10c). [115] AI is also promising in motivating the evolution of perception to cognition, having been demonstrated to distinguish materials through a single touch. [116] One concern in bioinspired self-healing materials is their mechanical performance.…”

Inspired by nature, various self-healing materials that can recover their physical properties after external damage have been developed. Recently, selfhealing materials have been widely used in electronic devices for improving durability and protecting the devices from failure during operation. Moreover, self-healing materials can integrate many other intriguing properties of biological systems, such as stretchability, mechanical toughness, adhesion, and structural coloration, providing additional fascinating experiences. All of these inspirations have attracted extensive research on bioinspired self-healing soft electronics. This review presents a detailed discussion on bioinspired self-healing soft electronics. Firstly, two main healing mechanisms are introduced. Then, four categories of self-healing materials in soft electronics, including insulators, semiconductors, electronic conductors, and ionic conductors, are reviewed, and their functions, working principles, and applications are summarized. Finally, human-inspired self-healing materials and animal-inspired self-healing materials as well as their applications, such as organic field-effect transistors (OFETs), pressure sensors, strain sensors, chemical sensors, triboelectric nanogenerators (TENGs), and soft actuators, are introduced. This cutting-edge and promising field is believed to stimulate more excellent cross-discipline works in material science, flexible electronics, and novel sensors, accelerating the development of applications in human motion monitoring, environmental sensing, information transmission, etc.

Triboelectric nanogenerators (TENGs) have gained significant traction in recent years in the bioengineering community. With the potential for expansive applications for biomedical use, many individuals and research groups have furthered their studies on the topic, in order to gain an understanding of how TENGs can contribute to healthcare. More specifically, there have been a number of recent studies focusing on implantable triboelectric nanogenerators (I‐TENGs) toward self‐powered cardiac systems healthcare. In this review, the progression of implantable TENGs for self‐powered cardiovascular healthcare, including self‐powered cardiac monitoring devices, self‐powered therapeutic devices, and power sources for cardiac pacemakers, will be systematically reviewed. Long‐term expectations of these implantable TENG devices through their biocompatibility and other utilization strategies will also be discussed.

“…[5] So far, with the help of 5G networks and the rapid rise of the Internet of Things, several TENG-based intelligent traffic monitoring systems have been constructed, including dual-type signal vector sensors for identifying vehicle direction and trajectory, [6] robust displacement sensors, [7] and sustainable monitoring smart transportation infrastructure skin. [8] However, most of these sensors are ineffective in handling traffic accidents and preventing drowsy driving. Furthermore, the absence of a self-healing function significantly reduces their service life.…”

A self‐powered and sustainable traffic monitoring system is highly required for future urban development. Herein, self‐healable piezoresistive sensors and triboelectric nanogenerators (TENGs) are constructed by in situ polymerization of polyvinyl alcohol‐polyacrylamide double network hydrogel in the presence of sodium alginate and tannic acid‐modified cellulose nanocrystals (denoted as PPC) for all‐weather self‐powered intelligent traffic monitoring applications. Because of hydrogen bonding and boron ester bonding, the resultant PPC‐based strain sensor can rapidly self‐heal and restore its sensing ability within 1 min with a self‐healing efficiency of 97.4%. Based on piezoresistive effect, the ions in sodium alginate endow the PPC‐based strain sensor with a relatively high gauge factor of 8.39, which can monitor the motion and fatigue of drivers. Based on triboelectrification effect, the PPC‐based TENG sensor can detect instantaneous vehicle speed, judge traffic accident liability, evaluate vehicle weight, and alert the driver to prevent accidents caused by drowsy driving. After partially replacing water in the PPC with glycerin, the resulting PPC‐based TENG sensor exhibits stable performance at temperatures ranging from ‐30 to 40 °C, ensuring its all‐weather monitoring ability. The all‐weather and self‐powered intelligent traffic monitoring system is promising for ensuring the security of future cities.
