Printing technology has revolutionized manufacturing by enabling high-volume, multipurpose, low-cost production with minimal environmental impact. This advancement has led to the integration of flexible electronic devices, such as displays, actuators, and sensors, into various consumer markets. Over the past few decades, printed electronics have garnered significant interest from both academic and industrial communities. Among these, flexible strain sensors stand out due to their adaptability and potential for large-scale applications. However, a comprehensive analysis of their sensing performance, particularly with respect to printability, remains lacking. This review aims to systematically explore the development of flexible strain sensors produced through printing technology, focusing on key aspects such as the formulation of conductive inks, the use of diverse substrate materials, and the challenges associated with printability. Additionally, it delves into the practical applications of these sensors across multiple industries. By providing an in-depth examination of these factors, this review offers valuable insights into the current state of printed electronics and highlights their future potential in advancing flexible sensing technologies.
印刷技术通过实现高产量、多用途、低成本生产且对环境影响最小，彻底改变了制造业。这一进步促使柔性电子设备，如显示器、致动器和传感器，融入各种消费市场。在过去几十年里，印刷电子技术引起了学术界和工业界的极大兴趣。其中，柔性应变传感器因其适应性和大规模应用潜力而脱颖而出。然而，对其传感性能，特别是在可印刷性方面，仍缺乏全面分析。本综述旨在系统地探讨通过印刷技术生产的柔性应变传感器的发展，重点关注导电油墨配方、多种基材材料的使用以及与可印刷性相关的挑战等关键方面。此外，还深入研究了这些传感器在多个行业的实际应用。通过对这些因素进行深入研究，本综述为印刷电子技术的现状提供了有价值的见解，并突出了它们在推动柔性传感技术方面的未来潜力。
