心血管疾病是全世界死亡的主要原因。连续心脏监测是检测不规则心跳并向患者提供早期预警的有效方法。然而，传统的心脏监测系统具有刚性接口和多个布线组件，这在长期连续监测患者时引起不适。为了解决这些问题，迫切需要灵活舒适的传感设备，它们还可以更好地匹配表皮的动态机械特性，以收集准确的心脏信号。在这篇综述中，我们讨论了心脏监测方法以及传统的心血管监测设备的主要机制的原理。基于关键的挑战和限制，我们提出了灵活的心脏传感设备的设计原则。综述了近年来基于各种纳米材料和结构设计的心脏传感器的研究进展，沿着介绍了各种纳米材料和结构设计的心脏传感器的制备方法。此外，机器学习的最新进展显着实现了一个新的传感平台，用于多方面评估心脏状态，因此进一步审查和讨论。这种设计灵活传感器和实施机器学习的策略提供了一种很有前途的方法，可以在有限或没有人为监督的情况下自动检测实时心脏异常，同时舒适且持续地监测患者的心脏健康状况。
Cardiovascular disease is the leading cause of death worldwide. Continuous heart monitoring is an effective approach in detecting irregular heartbeats and providing early warnings to patients. However, traditional cardiac monitoring systems have rigid interfaces and multiple wiring components that cause discomfort when contin-uously monitoring the patient long-term. To address those issues, flexible and comfortable sensing devices are critically needed, and they could also better match the dynamic mechanical properties of the epidermis to collect accurate cardiac signals. In this review, we discuss the principles of the major mechanisms of heart monitoring approaches as well as traditional cardiovascular monitoring devices. Based on key challenges and limitations, we propose design principles for flexible cardiac sensing devices. Recent progress of cardiac sensors based on various nanomaterials and structural designs are closely reviewed, along with the fabrication methods utilized. More-over, recent advances in machine learning have significantly implemented a new sensing platform for the multifaceted assessment of heart status, and thus is further reviewed and discussed. Such strategies for designing flexible sensors and implementing machine learning provide a promising means of automatically detecting real-time cardiac abnormalities with limited or no human supervision while comfortably and continuously moni-toring the patient's cardiac health.
