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.
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.
