Fiber sensor suitable for electrocardiogram and respiratory signal detection

Abstract

The invention relates to a fiber sensor suitable for electrocardiogram and respiratory signal detection. The fiber sensor comprises a bearing layer. The fiber sensor is characterized in that a mixed weaving layer is distributed on the bearing layer and formed by weaving metal wires and cloth fibers in a mixed mode, the mixed weaving layer is in a rectangular shape, and the width of the rectangular mixed weaving layer ranges from 2 cm to 3 cm; or the mixed weaving layer is in a circular shape, and the diameter of the circular mixed weaving layer ranges from 2 cm to 3 cm. Hence, the fiber dressing / wearing comfort is achieved, and the fiber sensor is suitable for monitoring vital signs of human bodies, especially infants. In addition, the appearance of the fiber sensor has no big difference with that of ordinary fibers, and the fiber sensor and the ordinary fibers both have better electrode conductivity; meanwhile, the fiber sensor has better universality and is suitable for various closed-fit wearable systems.

Description

technical field [0001] The invention relates to a sensor, in particular to a fiber sensor suitable for detecting electrocardiogram and respiratory signals. Background technique [0002] Infants and toddlers enter a light sleep state when they go to sleep. During light sleep, it will move its trunk and limbs and sob softly from time to time. The whole sleep process is not quiet, and it occasionally opens its eyes for a short time. It can cause startle action. About 1-2 hours after light sleep, they will enter deep sleep. Infants and young children in deep sleep are relatively quiet, their faces and limbs are in a relaxed state, and their breathing is very even. Parents or guardians will check from time to time, like obsessive-compulsive disorder, whether the infant kicks or rolls to make the quilt fall and catch a cold, or whether the quilt covers his face and causes suffocation, which not only affects the rest of the infant, but also Interfering with parent or caregiver r...

AI Technical Summary

Problems solved by technology

Parents or guardians will check from time to time like obsessive-compulsive disorder, whether the infant kicks or rolls to make the quilt fall and catch a cold, or whether the quilt covers his face and causes suffocation, which not only affects the rest of the infant, but also Interfere with parent or caregiver rest and performance

[0003] At the same time, in order to facilitate the monitoring of vital signs of infants and young children, sticky electrodes are often required, which is prone to generate large signal noise

More importantly, it is uncomfortable to wear, especially for the immature skin of infants and young children, it is prone to discomfort

[0004] Furthermore, the sensor structure for monitoring the vital signs of infants and young children provided by the prior art is too complicated, as provided in patent 201310146138.8, which includes a pressure sensor, a data collector, and a processor; the pressure sensor is arranged under the mattress , the data collector collects data from the pressure sensor, and the processor performs data processing, alarm and display on the data obtained by the data collector; the pressure sensor senses the breathing and movement of the infant and outputs a time-domain spectrum , the processor converts the time-domain spectrum into a frequency-domain spectrum, and judges whether the frequency-domain spectrum satisfies a predetermined step pattern, and judges and defines that the infant is in a sleep state when the frequency-domain spectrum satisfies the predetermined step pattern; The pressure sensor includes a piezoelectric electret film, a first metal ground electrode, a metal positive electrode, a first insulating isolation layer, and a second insulating isolation layer; the first insulating isolation layer and the second insulating isolation layer are arranged on the pressure On opposite sides of the electro-electret film, the first metal ground electrode is arranged between the piezoelectric electret film and the first insulating isolation layer, and the metal positive electrode is arranged between the piezoelectric electret film and the Between the second insulating isolation layer, the first metal ground electrode and the metal positive electrode are respectively electrically connected to the data collector

More importantly, it can only monitor sleep, but cannot realize ECG monitoring, and the scope of use is too narrow
