In the contemporary era, self-powered sensors have gained significant attention, particularly in the domains of wearable devices, flexible electronics, healthcare monitoring devices, and the Internet of Things (IoT). Among the most promising technologies for mechanical energy harvesting are piezoelectric nanogenerators (PENGs) and triboelectric nanogenerators (TENGs), both of which convert ambient mechanical energy into electrical energy. However, the electrical output from either PENGs or TENGs alone is often insufficient to meet the power requirements of electronic devices. To address this limitation, the integration of piezoelectric and triboelectric effects into a single system has led to the emergence of piezoelectric-triboelectric hybrid nanogenerators (PT-HNGs). These hybrid systems represent a new class of energy harvesting devices capable of significantly enhancing energy conversion efficiency and output performance. This review provides a comprehensive overview of recent progress in developing PT-HNGs, focusing on their underlying mechanisms, structural designs, coupling effects, performance optimization strategies, and diverse application potentials. It highlights the hybrid system's unique synergy and real-world applicability, aiming to fill a critical gap in the literature. In addition, the review discusses the existing challenges, future directions, and prospects for the commercialization of PT-HNG technology.
在当代，自供电传感器受到了广泛关注，尤其是在可穿戴设备、柔性电子、医疗监测设备和物联网（IoT）领域。在机械能收集最有前景的技术中，压电纳米发电机（PENGs）和摩擦电纳米发电机（TENGs）是其中两种，它们都能将环境机械能转化为电能。然而，单独的PENGs或TENGs的电输出往往不足以满足电子设备的功率需求。为了解决这一限制，将压电和摩擦电效应集成到一个单一系统中，导致了压电-摩擦电混合纳米发电机（PT-HNGs）的出现。这些混合系统代表了一类新型的能量收集设备，能够显著提高能量转换效率和输出性能。本文综述全面概述了PT-HNGs开发的最新进展，重点关注其潜在机制、结构设计、耦合效应、性能优化策略以及多样的应用潜力。它突出了混合系统独特的协同作用和实际适用性，旨在填补文献中的关键空白。此外，综述还讨论了PT-HNG技术商业化面临的现有挑战、未来方向和前景。
