Today, cardiovascular diseases threaten human health worldwide. In clinical practice, it has been concluded that analyzing the pulse waveform can provide clinically valuable information for the diagnosis of cardiovascular diseases. Accordingly, continuous and accurate monitoring of the pulse wave is essential for the prevention and detection of cardiovascular diseases. Wearable triboelectric nanogenerators (TENGs) are emerging as a pulse wave monitoring biotechnology due to their compelling characteristics, including being self-powered, light-weight, and wear-resistant, as well as featuring user-friendliness and superior sensitivity. Herein, a comprehensive review is conducted on the progress of wearable TENGs for pulse wave monitoring. Firstly, the four modes of operation of TENG are briefly described. Secondly, TENGs for pulse wave monitoring are classified into two categories, namely wearable flexible film-based TENG sensors and textile-based TENG sensors. Next, the materials, fabrication methods, working mechanisms, and experimental performance of various TENG-based sensors are summarized. It concludes by comparing the characteristics of the two types of TENGs and discussing the potential development and challenges of TENG-based sensors in the diagnosis of cardiovascular diseases and personalized healthcare.
今天，心血管疾病威胁着全世界人类的健康。在临床实践中，已经得出结论，分析脉搏波形可以为心血管疾病的诊断提供有临床价值的信息。因此，连续、准确地监测脉搏波对于心血管疾病的预防和检测至关重要。由于具有自供电、轻巧、耐磨、用户友好和高灵敏度等优势，可穿戴摩擦纳米发电机（TENG）作为一种脉搏波监测生物技术正在兴起。本文对可穿戴 TENG 用于脉搏波监测的研究进展进行了全面综述。首先，简要描述了 TENG 的四种工作模式。其次，将用于脉搏波监测的 TENG 分为两类，即可穿戴柔性薄膜 TENG 传感器和基于纺织品的 TENG 传感器。接下来，总结了各种基于 TENG 的传感器的材料、制造方法、工作机制和实验性能。最后，通过比较两种 TENG 的特点，讨论了基于 TENG 的传感器在心血管疾病诊断和个性化医疗保健方面的潜在发展和挑战。
