Abstract The triboelectric nanogenerator (TENG) is a promising technology with unique advantages for harvesting environmental high‐entropy energy like wind power. However, inefficient harvest devices have limited the operating speed and practical application of TENGs. In this work, bionic blade lift‐drag hybrid turbine‐driven triboelectric‐electromagnetic generator (HT‐TEHG) designed broadband harvesting. turbine combines benefits drag‐type blades enabling low start‐up lift‐type generating high torque, achieving an 11% increase in performance. TENGs are appropriate dielectric layer gaps to balance output performance friction torque independently driven by two types achieve self‐adaptive graded power generation at different speeds. starting HT‐TEHG 2 m s −1 achieves peak 202.4 mW conversion efficiency 9.1% 4 . durability TENG verified continuous operation 1 × 10 5 cycles almost no degradation. Moreover, can wireless weather station using natural wind. study introduces valuable approach enable distributed Internet Things devices.

Abstract Wind sensors have always played an irreplaceable role in environmental information monitoring and are expected to operate with lower power consumption extend service lifetime. Here, we propose a breeze wake-up anemometer (B-WA) based on rolling-bearing triboelectric nanogenerator (RB-TENG) extremely low static power. The B-WA consists of two RB-TENGs, self-waking-up module (SWM), signal processing (SPM), wireless transmission unit. RB-TENGs employed for system activation wind-speed sensing. Once the ambient exceeds 2 m/s, wake TENG (W-TENG) SWM can up within 0.96 s. At same time, SPM starts calculate frequency from measured (M-TENG) monitor wind speed sensitivity 9.45 Hz/(m/s). After stops, switch off 0.52 s decrease energy loss. In quiescent on-duty mode, operating is less than 30 nW, which greatly lifetime B-WA. By integrating devices rolling bearings, this work has realized ultralow self-waked-up system, foreseeable applications remote weather monitoring, IoT nodes, so on.

Triboelectric nanogenerators (TENGs) have garnered substantial attention in breeze wind energy harvesting. However, how to improve the output performance and reduce friction wear remain challenging. To this end, a blade-type triboelectric-electromagnetic hybrid generator (BT-TEHG) with double frequency up-conversion (DFUC) mechanism is proposed. The DFUC enables TENG high-frequency response that 15.9 300 times higher than excitation of 10 200 rpm. Coupled collisions between tribomaterials, surface charge density better generating are achieved. magnetization direction dimensional parameters BT-TEHG were optimized, its characteristics under varying rotational speeds electrical boundary conditions studied. At 2.2 m/s, can generate, respectively, power 1.30 19.01 mW. Further experimentation demonstrates capacity capacitors, light up emitting diodes (LEDs), wireless temperature humidity sensors. demonstrations show has great potential applications self-powered sensor networks (WSNs) for environmental monitoring intelligent agriculture.
