As the world is marching into the era of the Internet of things (IoTs) and artificial intelligence (AI), the most vital requirement for reliable hardware development is an ultrafast response time and no performance degradation. As a reliable indicator of human physiological health, blood pressure measurement is vital in humans' daily lives, which creates a huge demand in monitoring and diagnosing blood pressure problems. The triboelectric nanogenerator (TENG) is one of the best energy devices and healthcare applications in the new era since triboelectrification is a universal and ubiquitous effect with an abundant choice of materials. TENG is reliable in physiological monitoring applications and has many benefits, including being inexpensive, easy to manufacture, and lightweight, having self-powered properties, and being available in a wide range of materials. In this review, triboelectric nanogenerator based wrist pulse measurement was summarized for blood pressure monitoring and diagnosis applications. As per the Ayurveda, imbalance in three essential components of the wrist pulse implies the human health status and reveals symptoms for diseases. The design of different TENG-based blood pressure sensors, sensing mechanisms, performance, merits, and demerits of each method are discussed.
随着世界步入物联网（IoTs）和人工智能（AI）时代，可靠硬件开发的最重要要求是超快速响应时间且无性能下降。作为人类生理健康的可靠指标，血压测量在人们日常生活中至关重要，这在血压问题的监测和诊断方面产生了巨大需求。摩擦纳米发电机（TENG）是新时代最佳的能量装置和医疗保健应用之一，因为摩擦起电是一种普遍存在的效应，材料选择丰富。TENG在生理监测应用中可靠且有诸多优点，包括成本低廉、易于制造、重量轻、具有自供电特性以及有多种材料可供选择。在本综述中，总结了基于摩擦纳米发电机的腕部脉搏测量用于血压监测和诊断应用。根据阿育吠陀医学，腕部脉搏三个基本组成部分的失衡意味着人体健康状况并揭示疾病症状。讨论了不同基于TENG的血压传感器的设计、传感机制、性能、优点和缺点。
