Pulse wave carries comprehensive information regarding the human cardiovascular system (CS), which is essential for directly capturing CS parameters. More importantly, cuffless blood pressure (BP) is one of the most critical markers in CS. Accurately measuring BP via the pulse wave for continuous and noninvasive diagnosis of a disease associated with hypertension remains a challenge and highly desirable. Here, a flexible weaving constructed self‐powered pressure sensor (WCSPS) is reported for measurement of the pulse wave and BP in a noninvasive manner. The WCSPS holds an ultrasensitivity of 45.7 mV Pa⁻¹ with an ultrafast response time of less than 5 ms, and no performance degradation is observed after up to 40 000 motion cycles. Furthermore, a low power consumption sensor system is developed for precisely monitoring pulse wave from the fingertip, wrist, ear, and ankles. A practical measurement is performed with 100 people with ages spanning from 24 to 82 years and different health statuses. The discrepancy between the measured BP results using the WCSPS and that provided by the commercial cuff‐based device is about 0.87–3.65%. This work demonstrates an efficient and cost‐effective way for human health monitoring, which would be a competitive alternative to current complex cardiovascular monitoring systems.

柔性编织构造的自供电压力传感器，可实现心血管疾病的连续诊断和无袖带血压的测量

脉搏波携带有关人体心血管系统（CS）的全面信息，这对于直接捕获CS参数至关重要。更重要的是，无袖血压（BP）是CS中最关键的标志之一。通过脉搏波准确测量血压以连续和非侵入性地诊断与高血压有关的疾病仍然是一个挑战，也是非常需要的。在这里，报道了一种柔性编织构造的自供电压力传感器（WCSPS），以无创方式测量脉搏波和BP。WCSPS的超灵敏度为45.7 mV Pa ^-1响应时间小于5毫秒，并且经过多达40 000个运动循环后，没有观察到性能下降。此外，开发了一种低功耗传感器系统，用于精确监控来自指尖，手腕，耳朵和脚踝的脉搏波。实际测量是对100位年龄在24至82岁且健康状况不同的人进行的。使用WCSPS测得的BP结果与商用基于袖带的设备提供的BP之间的差异约为0.87–3.65％。这项工作展示了一种有效且经济高效的人类健康监测方法，它将是当前复杂的心血管监测系统的有竞争力的替代方案。
