High-temperature operatable triboelectric nanogenerator using microdome-patterned polyimide for self-powered sensors

Harsh Environmental-Tolerant and High-Performance Triboelectric Nanogenerator Based on Nanofiber/Microsphere Hybrid Membranes

“…From Figure 8 a,b, the HO-TENG based on FSHM prepared in this study has a small output voltage attenuation and an output efficiency of more than 77% when working at a high-temperature environment of 70 °C. As listed in Table 1 , compared with previous reports [ 36 , 37 , 39 , 44 , 68 , 69 ], the HO-TENG has a higher retention rate of electrical output performance in high-temperature environments and excellent high-temperature operability. In view of suppressing the electron thermionic emission of the triboelectric layer and improving the structural stability of triboelectric materials at high temperatures are the key to ensuring the efficient, stable and continuous operation of triboelectric materials in the changing environment, preparing the high-temperature operable TENG, and expanding its application fields.…”

“…In view of suppressing the electron thermionic emission of the triboelectric layer and improving the structural stability of triboelectric materials at high temperatures are the key to ensuring the efficient, stable and continuous operation of triboelectric materials in the changing environment, preparing the high-temperature operable TENG, and expanding its application fields. Through systematic literature research, we believe that the electrical output performance and operating temperature of high-temperature operable TENG devices can be further improved by adding high-temperature resistant dielectric filler to the triboelectric materials, using polymer materials with excellent thermal-resistance as the triboelectric layer, and and more refined micro/nanostructure design in subsequent studies [ 39 , 70 , 71 ], which is also the focus of our work in the future. In addition, as shown in Figure 8 c, the HO-TENG prepared in this study shows excellent charging characteristics for commercial capacitors under different temperature environments, which provides unlimited possibilities for HO-TENG electronic devices to be applied in harsh environments.…”

“…Recently, autonomous vehicles (driverless, autonomous, and robotic) that can sense the environment and navigate without human input based on artificial intelligence (AI) technology have proven to be innovative vehicles. Thereinto, the driving safety warning (DSEW) system is very important in the cruise of autonomous vehicles, which is a key technology proposed and rapidly developed in this field [ 39 , 40 ]. In fact, without a powerful and efficient sensor network, information cannot be provided.…”

Ultralight, Elastic, Hybrid Aerogel for Flexible/Wearable Piezoresistive Sensor and Solid–Solid/Gas–Solid Coupled Triboelectric Nanogenerator

“…Compared with the state‐of‐the‐art in the literature reports, the power density of GO/CNT HA‐TENG is relatively high (as shown in Table S1 in the Supporting Information). [ 38 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ] Finally, the GO/CNT HA‐TENG was used to charge commercial capacitors, as shown in Figure 5h . When the working frequency is 1 Hz, three different capacitors (0.22, 1.0, and 3.3 µF) could be charged for 60 s through the rectifier, and charge the voltage of the capacitor to 5.05, 2.47, and 1.66 V respectively.…”

3D nanocrystalline metal–organic framework materials for the improved output performance of triboelectric nanogenerators

“…In particular, nanotriboelectric material particles obtained by special methods could not only change the surface properties but also effectively increase the contact area, which improved the output power and achieved excellent performance. [14][15][16][17] In addition, the dominant polymers in the triboelectric material series are difficult to functionalize and modify to meet more complex application needs. Developing appropriate nanomaterials is the most effective way to fundamentally improve the TENG performance.…”
