... 32,39,40 Additionally, by introducing nonlinear factors, the piezoelectric energy harvester operates in multiple vibration modes, corresponding to a broad frequency bandwidth. 38,[41][42][43][44] This review starts by briefly introducing the energy flow from mechanical to electrical energy conversion in TENG systems. As a mechanical energy harvester, we focus on the dynamic behavior of TENGs combined with the spring force, magnetic force, and pendulum to enhance output performance. ...
... Some studies show that stress also potentiates anxiety and impairs emotion regulation [13][14][15]. The survey by Mao Yupeng et al. (2022) showed that the stress faced by Chinese female Ph.D. candidates made them more anxious [16]. A study by Yukihiro Suzuki et al. (2021) revealed an important mechanism of emotion regulation in response to stress, which reflects the level of modulation induced by a stressor [17]. ...
... The triboelectric nanogenerator (TENG) is based on coupling, the contact charge effect, and the electrostatic induction effect [37,38]. It has the advantages of simple manufacture, a wide selection of materials, diverse working modes, and excellent flexibility [39][40][41][42][43]. ...
... In recent years, with the rapid development of big data and the Internet of Things [1,2], the Internet of Things has been widely used in the fields of intelligent public transport, energy and environmental protection, security systems, biomedical and smart home, which not only solves the pain points of many industries, but also provides more convenience for people's lives [3][4][5][6][7][8][9][10]. Internet of Things technology is also affecting the field of sports. Based on big data analysis, some wearable electronic devices have been developed to monitor athletes' sports performance and daily training, which has become an effective means to improve athletes' competitive level [11][12][13][14][15][16][17][18]. For a long time, table tennis has been popular in the Olympic Games because of its fast pace of competition and complex and changeable technology. ...
... The triboelectric nanogenerator (TENG), invented by Zhonglin Wang, is a new potential energy conversion technology. TENG can transform neglected and widespread mechanical energy into electrical energy, which makes it possible to collect biological mechanical energy [19][20][21][22][23][24][25][26][27][28][29][30] and self-powered sensing [31][32][33][34][35][36]. ...
... The vast majority of people, even those of who are engaged in manual work, do not have well-developed pectoralis major muscles, unless they are deliberately exercising it. In fact, although Chinese people have come to gradually realize the importance of fitness, it has not been practiced for a long time (36,37). Therefore, according to our follow-up, there was no significant effect on upper limb movement. ...
... In 2012, Zhonglin Wang first proposed the concept of triboelectric nanogenerators (TENG) [28]. TENGs have shown many advantages, such as a low cost, easy fabrication, high power density, and a wide range of material choices, attracting the attention of many researchers [29][30][31][32]. They can collect and convert the low-frequency energy widely distributed in nature into electrical energy, which is an economic, green, and sustainable source of energy supply [33][34][35][36][37]. ...
... It is reported that some common items in life can be used as triboelectric materials for manufacturing TENGs, which provides great help for the collection of biomechanical energy, the detection of food quality, the provision of environmentally friendly energy, and the monitoring of human movement. For example, the latex film in a milk carton can be used to test the quality of food after being polished [21]; the waterproof function of the new nanocomposite material based on fabric can be used to collect the energy of wind and rain and sleep monitoring [22], and simple wearable devices can be attached to the human body and used in the monitoring of skating, basketball, Taekwondo and other sports scenes [23][24][25][26][27][28][29]. It has also been shown that: fiber/textile triboelectric nanogenerators can be used as human mechanical energy harvesters to provide mobile sustainable power for wearable electronic products [30]; new napkin-based triboelectric nanogenerators can be integrated into insoles to achieve physiological monitoring of the human body [31]; and by adjusting the weight percentage of expandable microspheres in the polydimethylsiloxane (PDMS) mixture, a sensitive triboelectric nanogenerator can be obtained, which can be used to monitor respiration and pulse [32]. ...
