Abstract

Currently, cardiovascular diseases such as hypertension and heart disease are one of the main causes of death. The existing blood pressure monitoring devices have a large volume or cannot achieve continuous blood pressure monitoring, which limits their application in early prevention. Here, a wearable health monitoring sensor based on CNT/Ecoflex porous composite material and pulse wave characteristic parameter prediction blood pressure model is proposed, which can achieve uninterrupted monitoring of blood pressure and heart rate. Based on the sensor, the predicted mean and standard deviations of systolic blood pressure (SBP) and diastolic blood pressure (DBP) from results of the standard blood pressure meter are 0.600 ± 4.251 and 0.580 ± 4.103 mm Hg, respectively. Based on this sensor, a portable device is developed for long-term blood pressure monitoring during human movement, which helps with early prevention and remote diagnosis.

基于柔性CNT/Ecoflex多孔复合材料的连续血压监测

目前，高血压、心脏病等心血管疾病是导致死亡的主要原因之一。现有的血压监测装置体积大或不能实现血压的连续监测，限制了其在早期预防中的应用。本文提出了一种基于CNT/Ecoflex多孔复合材料和脉搏波特征参数预测血压模型的可穿戴式健康监测传感器，可实现对血压和心率的不间断监测。基于该传感器，根据标准血压计结果预测的收缩压（SBP）和舒张压（DBP）均值和标准差分别为0.600 ± 4.251和0.580 ± 4.103 mm Hg。基于该传感器，开发了一种便携式设备，用于人体运动过程中的长期血压监测，有助于早期预防和远程诊断。

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
