“…TENG will undoubtedly provide a new power supply manner for intelligent, wearable, and implantable electronic products. To date, some wind energy harvesting TENGs with rotational structures [27][28][29][30] and flutter-driven structures were developed [31][32][33][34][35][36], and quite high outputs could be achieved under relatively high wind speeds which were usually higher than 5 m s −1 . However, the global average wind speed near the surface (the observation altitude is 10 meters) is reported to be 3.28 m s −1 [6,37].…”

proposed to harvest the ultrasonic wave's energy using zinc oxide (ZnO) nanowire arrays, [9] the nanogenerator has entered a period of rapid development. [10][11][12][13] Various energies have been harvested using many kinds of nanogenerators, [4] such as triboelectric nanogenerators, [13] PENGs, [14] thermal-electric nanogenerators, [15] and photoelectric nanogenerators. [16] In addition, the as-harvested energy has various resources, such as wind, [17][18][19] heat energy, [20,21] solar power, [22] vibration, [23,24] mechanical energy, [25] electromagnetic waves, [26] chemical energy, [27] and water energy. [11,28,29] Therein, the nanogengerator induced from water-flow [30][31][32][33][34] and water evaporation [29,35] is a majority part of the water energy nanogenerator. Generally, the energy-produced principle from water-flow and water evaporation could be divided into two categories according to the surface properties of the nanogenerator. On the one hand, as the ionic solution

“…The nitrogen gas was injected to the wind-TENG with different pressures of 0.05 MPa, 0.06 MPa, 0.07 MPa, 0.08 MPa, and 0.09 MPa which can be converted to speeds of 1.5 m/s, 1.8 m/s, 2.1 m/s, 2.4 m/s, and 2.7 m/s respectively, using an anemometer. These wind speeds were regarded as those under the average wind speed in our environment [35]. To show the advantage of this device structure, the output performances of the wind-TENG were observed at the wind speeds under the natural wind in our environment.…”

Wind is a great sustainable energy source for harvesting due to its abundant characteristic. Typically, large space, loud noise, and heavy equipment are essential for a general wind power plant and it is solely operated by big-scale wind. However, wind energy can be efficiently harvested by utilizing the triboelectric nanogenerator due to its abundance, ubiquity, and environmentally friendliness. Furthermore, a few previously reported wind-driven triboelectric nanogenerators, which have the bulk fluttering layer by wind, still show difficulty in generating electricity under the conditions of weak wind because of the static friction arisen from the inherent structure. In this case, the output performance is deteriorated as well as the generator cannot operate completely. In this work, a wind-driven triboelectric nanogenerator (wind-TENG) based on the fluttering of the PTFE strips is proposed to solve the aforementioned problems. At the minimum operating wind pressure of 0.05 MPa, this wind-driven TENG delivers the open-circuit voltage of 3.5 V, short-circuit current of 300 nA, and the associated output power density of 0.64 mW/m2 at the external load resistance of 5 MΩ. Such conditions can be used to light up seven LEDs. Moreover, this wind-TENG has been utilized as a direction sensor which can sense the direction at which the wind is applied. This work thus provides the potential application of the wind-TENG as both self-driven electronics and a self-powered sensor system for detecting the direction under environmental wind.
