“…The TENGs discussed in the above sections all act as self‐powered health monitors themselves. TENGs can also be integrated into self‐powered sensing systems with energy storage devices and health sensors to monitor health conditions such as heartbeat, pulse, body temperature, respiration, and lactate concentration . For example, body temperature is a vital sign, and monitoring body temperature is important for medical diagnosis and treatment.…”

“…Lactate level reflects important information of human health, and is a critical factor in conditions including hemorrhage, respiratory failure, hepatic disease, sepsis, and tissue hypoxia. Chen et al reported a TENG‐based self‐powered electrochemical system that can be able to detect the lactate concentration in human perspiration (Figure g,h) . The TENG uses nanostructured gelatin and PDMS as the two triboelectric layers and aluminum as the two corresponding electrodes.…”

Health monitoring helps prevent, diagnose, and treat diseases, and has been given more and more attention in recent years. Triboelectric nanogenerators (TENGs) are promising for applications in health monitoring due to their myriad of merits including low cost, simple fabrication, light weight, self-powered property, and wide selection of materials. Here, the recent key research achievements in TENG-based health monitoring are comprehensively reviewed. TENGs have been applied to detect not only motion-based health conditions such as pulse and heartbeat but also nonmotion-based health conditions such as CO 2 concentration and lactate concentration. The design of device structure, sensing mechanism, device performance, advantages and disadvantages of each kind of TENG-based health monitors are discussed. Based on recent progresses, the existing challenges and future prospects for TENG-based health monitoring are also discussed and summarized.

“…The signature fragment ion ( m / z 182.118) of cocaine, for example, can only be observed by this TENG‐based system, instead of the traditional system. With respect to sensors, some devices require the charge generated by contact electrification to be controlled . For example, sensing of CO 2 can be achieved by controlling the amount of charge generated via contact electrification (Figure c) .…”

Contact electrification is the phenomenon in which charge is generated on the surfaces of materials after they come into contact. The surface charge generated has traditionally been known to cause a vast range of undesirable consequences in our lives and in industry; on the other hand, it can also give rise to many types of useful applications. In addition, there has been a lot of interest in recent years for fabricating devices and materials based on regulating a desired amount of surface charge. It is thus important to understand the general strategies for increasing, decreasing, or controlling the surface charge generated by contact electrification. Herein, the fundamental mechanisms for influencing the amount of charge generated, the methods used for implementing these mechanisms, and some of the recent interesting applications that require regulating the amount of surface charge generated by contact electrification, are briefly summarized.

“…Nevertheless, commercialized portable energy storage units including batteries and supercapacitors are relatively heavy, charged frequently, and face critical lifetime limitation [8][9][10]. To overcome these challenges, a series of advanced energyharvesting technologies based on triboelectric, photovoltaic, and thermoelectric effects from ambient environment for sustainable and portable power source have been developed [11][12][13][14][15].…”

HIGHLIGHTS• Owing to the great robustness, continuous conductivity, and geometric construction of a steel wire electrode, the FST-TENGs demonstrate high stability, stretchability, and even tailorability.• By knitting several FST-TENGs to be a fabric or a bracelet worn on the human body, it enables to harvest human motion energy.• The FST-TENGs can also be woven on dorsum of glove to monitor the movements of gesture.ABSTRACT Continuous deforming always leads to the performance degradation of a flexible triboelectric nanogenerator due to the Young's modulus mismatch of different functional layers. In this work, we fabricated a fiber-shaped stretchable and tailorable triboelectric nanogenerator (FST-TENG) based on the geometric construction of a steel wire as electrode and ingenious selection of silicone rubber as triboelectric layer.Owing to the great robustness and continuous conductivity, the FST-TENGs demonstrate high stability, stretchability, and even tailorability. For a single device with ~ 6 cm in length and ~ 3 mm in diameter, the open-circuit voltage of ~ 59.7 V, transferred charge of ~ 23.7 nC, short-circuit current of ~ 2.67 μA and average power of ~ 2.13 μW can be obtained at 2.5 Hz. By knitting several FST-TENGs to be a fabric or a bracelet, it enables to harvest human motion energy and then to drive a wearable electronic device. Finally, it can also be woven on dorsum of glove to monitor the movements of gesture, which can recognize every single finger, different bending angle, and numbers of bent finger by analyzing voltage signals.
