Abstract

The growing global demand for sustainable and portable energy solutions has fueled research into nanogenerators (NGs), primarily those leveraging piezoelectric effects for energy harvesting. The increasing demand for biodegradable (BD), biocompatible, wearable, and flexible electronics has driven the development of advanced NGs, capable of converting mechanical, frictional, or thermal energy into electrical power. Piezoelectric NGs (PENGs), utilizing 2D hybrid (HD) and BD components, offer a promising path towards next-generation self-powered devices combining high-performance energy harvesting systems with environmental sustainability, making them ideal for innovative and eco-friendly electronics. Compared to traditional materials, 2D HD offers atomic-scale thickness, high mechanical strength, and intrinsic piezoelectric properties at the monolayer level. Integration of 2D HD with BD substrates enables the fabrication of fully degradable, biocompatible, and flexible/non-flexible devices capable of harvesting energy from mechanical motions, such as vibrations, bending, or body movement. This review highlights the latest developments in 2D HD and BD materials for flexible/non-flexible PENGs, focusing on their design, working principles, and application in real-time sensing and self-powered electronics. Special emphasis is given to material innovations, structural configurations, and the role of biodegradability in enhancing device sustainability. Current challenges and prospects are also discussed for scalable and reliable BD-based self-powered systems tailored for next-generation sustainable energy technologies.

用于自供电系统的二维混合可生物降解压电纳米发电机：新一代可持续能源

全球对可持续和便携式能源解决方案的需求不断增长，推动了纳米发电机（NGs）的研究，主要是利用压电效应进行能量收集的纳米发电机。对生物可降解（BD）、生物相容性、可穿戴和柔性电子产品日益增长的需求推动了先进的ngg的发展，能够将机械能、摩擦力或热能转化为电能。利用2D混合（HD）和BD组件的压电NGs （PENGs）为下一代自供电设备提供了一条有前途的道路，将高性能能量收集系统与环境可持续性相结合，使其成为创新和环保电子产品的理想选择。与传统材料相比，2D HD具有原子级厚度、高机械强度和单层固有压电特性。2D HD与BD基板的集成使制造完全可降解，生物相容性和柔性/非柔性设备能够从机械运动（如振动，弯曲或身体运动）中收集能量。本文综述了用于柔性/非柔性peng的2D HD和BD材料的最新进展，重点介绍了它们的设计、工作原理以及在实时传感和自供电电子中的应用。特别强调的是材料创新，结构配置，以及生物降解性在提高设备可持续性中的作用。本文还讨论了为下一代可持续能源技术量身定制的可扩展、可靠的基于bd的自供电系统的当前挑战和前景。
