Wearable physiological sign detection sensor, preparation method and monitoring system

Abstract

The invention relates to the physiological monitoring field and discloses a wearable physiological sign detection sensor, a preparation method for the wearable physiological sign detection sensor and a monitoring system based on the wearable physiological sign detection sensor. The wearable physiological sign detection sensor is used for monitoring heart rate and respiratory rate. The wearable physiological sign detection sensor comprises a fabric object, a support layer, a sensitive material layer, an electrode layer and a protection layer, wherein the sensitive material layer is made of three-dimensional porous nanometer sensitive material, the protection layer and the support layer are made of flexible high-molecular polymer and have bio-compatibility, and the protection layer and the support layer together package the sensitive material layer. The wearable physiological sign detection sensor is light, thin and soft; the wearable physiological sign detection sensor can be processed into different shapes, and the wearable physiological sign detection sensor can attach to the skin surface or be worn at the skin surface; the wearable physiological sign detection sensor is capable of gathering the chest heart rate and respiratory rate data through integrating on the fabric in contact with the heartbeat region of the chest so as to effectively monitor the heartbeat information.

Description

technical field [0001] The invention relates to the field of physiological monitoring, in particular to a wearable physiological sign detection sensor, a preparation method and a monitoring system thereof. Background technique [0002] Heart rate and respiratory rate are one of the important physiological parameters of the human body. Real-time monitoring of them provides users with useful physiological health information, which will be of great value to users' health assessment and early prevention of diseases (such as cardiovascular system diseases) . [0003] At present, there are many traditional medical instruments for monitoring heart rate, and the common detection devices are based on pressure sensors, photoelectric sensors, capacitive sensors and electroacoustic sensors. In ancient China, pulse diagnosis was used to detect the heartbeat frequency. Although the method is simple and convenient, the correctness of the diagnosis mainly depends on the doctor's experience...

AI Technical Summary

Problems solved by technology

[0004] At present, there are also some reports on wearable medical fabrics used to monitor physiological signals at home and abroad, such as the "life shirt" developed by VivoMetrics in the United States, which can reflect the wearer's breathing situation and record the body's body position changes, but it is not easy to wear and complicated to operate. , Not suitable for use in daily life and work; Italian company Milior of Prado combines smart sensors in the form of fibers or yarns with fabric technology to monitor breathing and body temperature, but the price is high and the comfort of wearing in daily life is not good , affecting its practicability; the T-shirt with sensing function developed by Germany's Fraunhofer IZM can detect the wearer's cardiac electrophysiological parameters, but long-term contact with the skin will cause skin ulceration

Other instruments used for heart rate and respiratory rate detection in the prior art also have problems such as complicated operation, high cost, inconvenient to carry, unable to meet daily monitoring needs, poor biocompatibility, uncomfortable to wear, etc.

[0005] The key to the new heart rate and respiratory rate monitoring technology lies in the preparation of sensors. The survey found that wearable electronic fabrics currently used to collect heart rate and respiratory rate and professional wearable devices that judge human physiological health through the analysis of chest heartbeat signals There are few fabrics, and there are few that can meet the daily monitoring needs of ordinary people anytime, anywhere. Therefore, it is particularly important to develop an intelligent, popular, scientific and convenient heart rate and respiratory rate monitoring tool.
