Sensor networks are essential for the development of the Internet of Things and the smart city. A general sensor, especially a mobile sensor, has to be driven by a power unit. When considering the high mobility, wide distribution and wireless operation of the sensors, their sustainable operation remains a critical challenge owing to the limited lifetime of an energy storage unit. In 2006, Wang proposed the concept of self-powered sensors/system, which harvests ambient energy to continuously drive a sensor without the use of an external power source. Based on the piezoelectric nanogenerator (PENG) and triboelectric nanogenerator (TENG), extensive studies have focused on self-powered sensors. TENG and PENG, as effective mechanical-to-electricity energy conversion technologies, have been used not only as power sources but also as active sensing devices in many application fields, including physical sensors, wearable devices, biomedical and health care, human–machine interface, chemical and environmental monitoring, smart traffic, smart cities, robotics, and fiber and fabric sensors. In this review, we systematically summarize the progress made by TENG and PENG in those application fields. A perspective will be given about the future of self-powered sensors.

“…[26][27][28][29] The TTEG has been demonstrated to harvest mechanical energies of human motions, aiming to be wearable power sources or active self-powered sensors. [30][31][32][33][34][35][36][37][38] Ever since the first report of the triboelectric nanogenerator (TENG) in 2012 by Wang et al, the areal output power density reaches 500 W/m 2 , and the efficiency of TENGs can be up to 85% or higher based on a and well-controlled and extremely small mechanical input. 39,40 However, such small mechanical input rarely exists in our daily life.…”

Large-area, flexible, and lightweight textile-based triboelectric generator (TTEG) technologies are promising power supplier by harvesting energy from human motions, wind, and water current. Numerous TTEG systems have been demonstrated. However, the challenges in their applications include the low electric output power, failure under wearing conditions, and adverse effects on the wearable performance like comfort and durability. What is the influence of system integration on the output performance of the TTEGs? What kinds of textile-structures have the most promising performance? How to make an effective TTEG system? In an attempt to answer these important questions, a critical review is presented on the recent advances of wearable TTEG systems in terms of textile structures, selection of materials, working modes, mechanisms of triboelectrification and charge transfer, energy storage, and their integrations. Furthermore, the major approaches or directions for improving the total conversion efficiency and performance of wearable TTEG systems are systematically summarized.

“…To obtain wide applications in knitted textiles, coaxial structural fibers in single electrode mode are usually designed. It is a conventional method to wrap conductive fiber for achieving the coaxial structure, and there are many yarns used such as stainless steel fibers 98 (Figure 4(a)), polyamide fiber coated by Ag 99 (Figure 4(b)). Then the double helix structure is also the common combination approach of coaxial yarns.…”

Advanced triboelectric nanogenerator techniques provide a massive opportunity for the development of new generation wearable electronics, which toward multi-function and self-powering. Textiles have been refreshed with the requirement of flexible electronics in recent decades. In particular, knitted-textiles have exhibited enormous and prominent potential possibilities for smart wearable devices, which are based on the merits of high stretchability, excellent elasticity, comfortability as well as compatibility. Combined knitted textiles with nanogenerator techniques will promote the knitted textile triboelectric nanogenerators (KNGs) emerging, endowing conventional textiles with biomechanical energy harvesting and sensing energy supplied abilities. However, the design of KNGs and the construction of KNGs are based on features of human motions symbolizing considerable challenges in both high efficiency and excellent comfort. Currently, this review is concerned with KNGs construction account of triboelectric effects referring to knitted-textile classifications, structural features, human motion energy traits, working mechanisms, and practical applications. Moreover, the remaining challenges of industrial production and the future prospects of knitted-textile triboelectric nanogenerators of harvesting biomechanical energy are presented.
