Abstract
As a sustainable energy source, sound is abundant in the environment, but its effective conversion into electrical energy remains a technical challenge. Triboelectric nanogenerators (TENGs) have made significant progress in addressing this issue, enabling the efficient capture of low-frequency sound waves and their transformation into usable power. This review explores the core principles behind acoustic energy harvesting using TENGs and examines key advancements in materials and resonator designs, including Helmholtz and quarter-wavelength configurations, which enhance energy conversion. Recent breakthroughs in TENG technologies are also highlighted, focusing on specialized mechanisms and innovative structural designs that improve sound wave collection and energy transfer. The review also looks into the various applications of TENGs, including harnessing urban noise, enhancing voice recognition systems, and powering wearable devices. Finally, challenges and future directions for expanding the use of acoustic energy harvesting technologies are discussed,focusing on their potential to provide practical and scalable energy solutions for various applications.
作为一种可持续能源,声音在环境中含量丰富,但将其有效转化为电能仍是一项技术挑战。三电纳米发电机(TENGs)在解决这一问题方面取得了重大进展,能够有效捕捉低频声波并将其转化为可用电能。这篇综述探讨了使用 TENGs 收集声能背后的核心原理,并研究了材料和谐振器设计方面的主要进展,包括能增强能量转换的赫尔姆霍兹和四分之一波长配置。此外,还重点介绍了最近在 TENG 技术方面取得的突破,重点关注可改善声波收集和能量传递的专门机制和创新结构设计。综述还探讨了 TENG 的各种应用,包括利用城市噪音、增强语音识别系统和为可穿戴设备供电。最后,还讨论了扩大声能收集技术应用的挑战和未来方向,重点关注其为各种应用提供实用、可扩展的能源解决方案的潜力。
期刊介绍:
In 1985, the Journal of Science was founded as a platform for publishing national and international research papers across various disciplines, including natural sciences, technology, social sciences, and humanities. Over the years, the journal has experienced remarkable growth in terms of quality, size, and scope. Today, it encompasses a diverse range of publications dedicated to academic research.
Considering the rapid expansion of materials science, we are pleased to introduce the Journal of Science: Advanced Materials and Devices. This new addition to our journal series offers researchers an exciting opportunity to publish their work on all aspects of materials science and technology within the esteemed Journal of Science.
With this development, we aim to revolutionize the way research in materials science is expressed and organized, further strengthening our commitment to promoting outstanding research across various scientific and technological fields.
