Ultrahigh Performance, Serially Stackable, Breeze Driven Triboelectric Generator via Ambient Air Ionizing Channel

Abstract

Currently, wind energy harvesting is in the limelight. However, with the existing electromagnetic wind generators, it is difficult to harvest multifariously‐wasted breezes. To harvest energy from winds at a wide range of speeds, wind‐driven triboelectric nanogenerators (TENGs) are studied. However, a critical limitation of general wind‐driven TENGs is that their power output is low. Therefore, an innovative strategy is necessary to generate high output power even from breeze. Herein, an approach to test a charge‐polarization‐based flutter‐driven TENG (CPF‐TENG) with ambient air ionizing channel (AAIC) is reported. Owing to AAIC, the device generates peak voltage and current outputs of 2000 V and 4 A, respectively. Moreover, because the proposed CPF‐TENG can generate power from breeze, it can be stacked in series to completely harvest wind energy. The stacked CPF‐TENG is demonstrated to operate 3000 light‐emitting diodes (LEDs) and 12 hygrometers, separately, and produce hydrogen at a rate of 342.3 µL h−1 with the electrolysis cell.

Fluid-based triboelectric nanogenerators: unveiling the prolific landscape of renewable energy harvesting and beyond

“…At a wind speed of 6 m s −1 , this configuration achieves a peak output power of 38.16 mW. Similarly, Son et al 88 proposed a flutter-TENG with an ambient air ionizing channel (AAIC). When linked to the electrodes, it efficiently segregates the opposing charges of the flutter-TENG, resulting in the accumulation of positive and negative charges at both ends of the AAIC.…”

“…By continuously receiving and analyzing wind-speed information from distributed wireless sensing nodes, meteorological departments can publish weather forecasts early to guide agricultural production and prevent natural disasters 9 – 12 . To date, widely distributed anemometers are powered mainly by batteries with limited working lifetimes and expensive maintenance costs 13 – 15 . To extend the service lifespan, the power consumption of anemometers needs to be further reduced.…”
