“…The testing characteristics (frequency, amplitude, and resulting force) difference between two systems is the important reasons for the difference of the corresponding output performance, but the water screening effect and complex electromagnetic field partition are also the reasons for this difference according to previous researches. [35,36] As the heuristic work about the TENG applying on the undersea energy harvest, the corresponding feasibility has been verified. The BFM-TENG not only has the potential to harvest undersea blue energy on a large scale, but also has the potential to develop new bionic-wing-structure TENG with optimized structure for wind energy harvesting.…”

In situ harvesting undersea energy is a vital method for undersea detector to realize its long‐term and real‐time undersea research. Herein, inspired by the fins with excellent hydrodynamic characteristic and the triboelectric nanogenerator (TENG) with the merits of light‐weight and high‐efficiency at low frequency, an energy harvesting device is designed to harvest undersea energy by bionic‐fin‐structure assisted with multilayer‐structured triboelectric nanogenerator (BFM‐TENG). The good design of geometry and structure enable BFM‐TENG to harvest energy efficiently by the driving of water‐flow from multidirections. Besides, based on the multiarea contact structure and ultrathin dielectric material, the BFM‐TENG could achieve a peak power density of 444 W m−3 under ideal test condition, which is about 1–2 orders of magnitude higher than that of previous work for harvesting wave energy. The findings not only provide a new in situ undersea energy harvesting method for undersea detectors to realize the real‐time, long‐term, and self‐powered undersea research, but also provide a potential strategy to achieve large‐scale undersea energy harvesting.

“…Besides, mechanical energy is also ubiquitously available in ambient and has been considered as another promising power source for self‐sustainable wearable and implantable electronics 281,282 . A high‐output magneto‐mechano‐triboelectric nanogenerator that can generate electricity from the alternating magnetic field has been reported lately, and it can successfully power up an indoor wireless positioning system as shown in Figure 9B 283 . The generated electrical energy is connected to a storage unit through a power management circuit, which enables the continuous operation of an IoT Bluetooth beacon for wireless signal transmission.…”

The past few years have witnessed the significant impacts of wearable electronics/photonics on various aspects of our daily life, for example, healthcare monitoring and treatment, ambient monitoring, soft robotics, prosthetics, flexible display, communication, human‐machine interactions, and so on. According to the development in recent years, the next‐generation wearable electronics and photonics are advancing rapidly toward the era of artificial intelligence (AI) and internet of things (IoT), to achieve a higher level of comfort, convenience, connection, and intelligence. Herein, this review provides an opportune overview of the recent progress in wearable electronics, photonics, and systems, in terms of emerging materials, transducing mechanisms, structural configurations, applications, and their further integration with other technologies. First, development of general wearable electronics and photonics is summarized for the applications of physical sensing, chemical sensing, human‐machine interaction, display, communication, and so on. Then self‐sustainable wearable electronics/photonics and systems are discussed based on system integration with energy harvesting and storage technologies. Next, technology fusion of wearable systems and AI is reviewed, showing the emergence and rapid development of intelligent/smart systems. In the last section of this review, perspectives about the future development trends of the next‐generation wearable electronics/photonics are provided, that is, toward multifunctional, self‐sustainable, and intelligent wearable systems in the AI/IoT era.

“…Triboelectric nanogenerators (TENGs) and piezoelectric nanogenerators harvest energy from the motion of organs; optical devices, ultrasound devices, and electromagnetic coils receive energy wirelessly by a transcutaneous approach; and biofuel cells extract energy from the redox reaction of glucose and electrolytes in the gastrointestinal tract [ 12 ]. Among all these methods, a TENG is the onlymethod to achieve direct nerve stimulations [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], showing its capability in the realization of a self-powered neuroprosthetic system in the future, which is far beyond the application of energy harvesting and self-powered physical and chemical sensing [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ].…”

Neuroprosthetics have become a powerful toolkit for clinical interventions of various diseases that affect the central nervous or peripheral nervous systems, such as deep brain stimulation (DBS), functional electrical stimulation (FES), and vagus nerve stimulation (VNS), by electrically stimulating different neuronal structures. To prolong the lifetime of implanted devices, researchers have developed power sources with different approaches. Among them, the triboelectric nanogenerator (TENG) is the only one to achieve direct nerve stimulations, showing great potential in the realization of a self-powered neuroprosthetic system in the future. In this review, the current development and progress of the TENG-based stimulation of various kinds of nervous systems are systematically summarized. Then, based on the requirements of the neuroprosthetic system in a real application and the development of current techniques, a perspective of a more sophisticated neuroprosthetic system is proposed, which includes components of a thin-film TENG device with a biocompatible package, an amplification circuit to enhance the output, and a self-powered high-frequency switch to generate high-frequency current pulses for nerve stimulations. Then, we review and evaluate the recent development and progress of each part.
