“…It works based on the effect of aeroelastic flutter due to the coupling of aerodynamic force and elastic deformation. [54][55][56][57][58][59] Specifically, when the energy of air flow exceeds the mechanical damping of the triboelectric beam, beam vibration could be sustained with a large amplitude that drives the beam to touch the package case, resulting in triboelectrification between the beam and the case.…”

As a fundamental and ubiquitous body motion, respiration offers a large amount of biomechanical energy with an average power up to the Watt level through movements of multiple muscles. The energy from respiration featured with excellent stability, accessibility and continuality inspires the design and engineering of biomechanical energy harvesting devices, such as triboelectric nanogenerators (TENGs), to realize human‐powered electronics. This review article is thus dedicated to the emerging respiration‐driven TENG technology, covering fundamentals, applications, and perspectives. Specifically, the human breathing mechanics are first introduced serving as the base for the developments of TENG devices with different configurations. Biomedical applications including electrical energy generation, healthcare monitoring, air filtration, gas sensing, electrostimulation, and powering implantable medical devices are then analyzed focusing on the design‐application relationships. At last, current developments are summarized and critical challenges for driving these intriguing developments toward practical applications are discussed together with promising solutions.

“…To resolve this problem, the triboelectric nanogenerator (TENG) was first proposed in 2012 by Zhonglin Wang 1 . TENGs have the ability to harvest natural mechanical energies, 2,3 such as wind energy, 4,5 water wave energy, 6 human body motions, 7‐9 traffic noises, etc., and convert them into electricity. Human itself is not only a rich source of mechanical energy, such as walking, running, joint motion, blood flow, and heart beats, but also the application terminal of wearable electronics; it is an ideal scheme to collect human energy and supply power for wearable electronics.…”

Summary With the growing demand for wearable electronic devices, triboelectric nanogenerators (TENGs) provide an effective solution by harvesting human body motions and converting them into electricity. Tribomaterial is one key element for the output performance and application of TENGs. In this study, biomaterial eggshell membrane (ESM) was investigated for use as a piezoelectric‐enhanced positive tribomaterial. ESM not only exhibits excellent piezoelectricity due to the amount of hydrogen bonds, but it is also biocompatible and pollution free. The piezoelectricities of raw eggshell membrane (RESM), heated eggshell membrane (HESM), and carbonized eggshell membrane (CESM) were analyzed and compared. Porous expanded polytetrafluoroethylene (ePTFE) was fabricated and used as a negative tribomaterial in the TENG due to its strong electron‐acquisition ability. Pairing ESM with an ePTFE resulted in a novel piezoelectric‐enhanced triboelectric bio‐nanogenerator (P‐TENG) with an excellent energy harvesting ability, high‐efficiency output performance, and sensitive human motion monitoring. By comparing ePTFE paired with RESM, HESM, and CESM, the CESM/ePTFE P‐TENG showed the best output performance due to CESM's piezoelectric enhancement. This bio‐P‐TENG as a wearable electric device has great potential in biomedical applications.

Wind is one of the most important sources of green energy, but the current technology for harvesting wind energy is only effective when the wind speed is beyond 3.5–4.0 m s−1. This is mainly due to the limitation that the electromagnetic generator works best at high frequency. This means that light breezes cannot reach the wind velocity threshold of current wind turbines. Here, a high‐performance triboelectric nanogenerator (TENG) for efficiently harvesting energy from an ambient gentle wind, especially for speeds below 3 m s−1 is reported, by taking advantage of the relative high efficiency of TENGs at low‐frequency. Attributed to the multiplied‐frequency vibration of ultra‐stretchable and perforated electrodes, an average output of 20 mW m−3 can be achieved with inlet wind speed of 0.7 m s−1, while an average energy conversion efficiency of 7.8% at wind speed of 2.5 m s−1 is reached. A self‐charging power package is developed and the applicability of the TENG in various light breezes is demonstrated. This work demonstrates the advantages of TENG technology for breeze energy exploitation and proposes an effective supplementary approach for current employed wind turbines and micro energy structure.
