“…A self-powered triboelectric palm-like tactile sensor is developed by Xu et al to construct a tactile perceptual system for undersea vehicles, which is fabricated by a 3D structure that mimics the leathery, granular texture in the palms of sea otters (Figure 17c). [186] The device of inner neural architecture offers additional clues to show the importance of tactile information. With the help of TENG technology and palm structure, the sensor has the function to estimate shear and normal external load in real-time and measure the external stimulation area.…”

The ocean, as one of the most important areas for human production and living, plays a vital role in transportation, food production, and energy supply. However, it is greatly desired to develop relevant advanced technologies to achieve efficient and safe ocean exploitation and utilization. The advanced triboelectric nanogenerator (TENG), which can transform mechanical motion into electric energy to achieve the harvesting of related mechanical energy and obtain corresponding mechanical motion characteristics by the corresponding electronic signal, is a significant choice to develop the corresponding advanced technologies for marine exploitation. According to the application field, TENG based marine exploitation researches can be divided into three kinds of researching directions, which contain the in situ ocean energy harvesting, self‐powered ocean monitoring, and self‐powered marine electrochemical technologies. The latest representative research works, which are based on TENG technology for marine exploitation, are classified in detail and summarized comprehensively in this review. More importantly, the specific prospects of TENG in the marine exploitation are discussed in detail to promote future research.

“…Therefore, smart and precise tactile sensors are crucial for accurate ocean exploration missions. [531] Inspired by the whisker structure of marine animals, Liu et al [511] proposed a bionic whisker sensor based on TENG to assist underwater robots to perceive the environment, as shown in Figure 13j. The sensor consists of a carbon fiber rod, an epoxy resin matrix, and four TENG sensing units.…”

With the rapid development of the Internet of Things (IoTs), numerous distributed wide‐area low‐power electronic devices have been utilized in various fields, such as wireless monitoring sensors and wearable electronics. Due to the dispersion and mobility of microelectronic devices, their energy supply faces serious challenges. The inconvenience and non‐environmental friendliness of using traditional centralized low entropy energy and chemical batteries to power distributed microelectronic devices are becoming increasingly prominent. Environmental energy harvesting technology with high entropy characteristics is considered an effective solution for low‐power electronic devices. This paper comprehensively reviews the recent progress in microelectronic technologies based on energy harvesting and signal sensing. First, state‐of‐the‐art micro‐power electronic devices in humans, animals, and the environment are introduced. Secondly, the available micro‐energy sources in the environmentare elaborated and summarized. Then, the principles and characteristics of ambient microenergy harvesting technologies based on different mechanisms are classified, summarized, and analyzed. In addition, this work comprehensively summarizes the applications of self‐powered micro‐electronics technology in 11 different fields, including human, animal, and environment. Finally, research challenges, technical difficulties, and research gaps in self‐powered microelectronics based on micro‐energy harvesting technology are discussed and summarized.

“…[1][2][3][4][5] Attaching wearable devices to the cloth or skin can directly obtain signal feedback synchronized with human motion, achieving real-time monitoring of the motion behaviors. As a sustainable energy harvesting device, a triboelectric nanogenerator (TENG) can transfer various kinds of green energy (e.g., wind, wave, vibration, or human mechanical motion) into output electrical signals, which can be beneficial to get rid of the battery power supplies and realize self-powered tactile sensing, [6,7] motion recognition, [8,9] human-machine interfacing, [10,11] and disease diagnosis. [12] Actually, wearable devices are easy to germinate bacteria after long-term contact with human skin, so permeability and antibacterial properties of the materials are highly required.…”

High flexibility, porosity, and antibacterial activity are extremely desired for wearable health monitoring, which is beneficial to simultaneously promote wearing comfort and safety. In this study, an antibacterial nanofibers‐based triboelectric generator (AN‐TENG) composed of the flexible chitosan/polyvinylpyrrolidone modified with halloysite nanotubes (CTS/PVP/HNTs) nanofibers and cube‐arrays structured Ecoflex film is proposed for simultaneously energy harvesting and self‐powered human motion monitoring. The open‐circuit voltage (280 V), short‐circuit current (3.98 μA), and transferred charge (51 nC) of the CTS/PVP/HNTs nanofibers TENG at the optimal compound concentration are increased by 90.8%, 86.92%, and 96.2%, respectively, compared to the CTS/PVP nanofibers one (size: 3 cm × 3 cm, mechanical force: 10 N @1 Hz), revealing good real‐time monitoring ability for human wrist, elbow, and finger motion. An antibacterial test is carried out to evaluate the antibacterial activity and the antibacterial rate of the nanofibers against Escherichia coli (ATCC 8739) and Staphylococcus aureus (ATCC 6538) based on the current national standard GB/T 31402–2015, indicating good antibacterial properties of the nanofibers. This research offers an ingenious strategy to establish an antibacterial nanofibers‐based TENG for self‐powered motion monitoring and energy harvesting and offers a new insight to improve the practical security of wearable electronic devices.
