High-deformation strain sensor based baby sleep respiration monitoring device

Abstract

The invention provides a high-deformation strain sensor based baby sleep respiration monitoring device. The monitoring device includes three portions: a data acquisition unit, a data processing unit,and an intelligent terminal unit; the data acquisition unit is formed by a high-deformation strain sensor is integrated on a baby clothing or garment, and is used for acquiring abdomen deformation data while a baby breathes; the data processing unit includes a microcontroller, a storage module, a wireless communication module, and a power supply module, is integrated on the baby clothing or garment, and is used for processing the acquired data and sending the data to the intelligent terminal of a guardian; and the intelligent terminal unit can display real-time baby respiration conditions andsend an alarm to the guardian through threshold determination. The monitoring device can monitor the sleep respiration condition of a baby in real time, can prevent emergencies while the baby has a sleep, and can relieve the pressure that the guardian takes care of the baby.

Description

technical field [0001] The invention relates to the field of sensor applications, in particular to a baby sleep respiration monitoring device based on a high-deformation strain sensor. Background technique [0002] As the country fully liberalizes the two-child policy, the number of newborns is increasing. Since babies are a special group, they have not formed a complete consciousness, nor have the ability to independently express their personal will, so guardians are required to pay close attention to every move of babies anytime, anywhere. Especially at night, the guardian should pay special attention to the sleep status of the baby. In this way, the guardian will not only feel very tired because of frequently looking at the baby, but also may not be able to discover the unexpected situation of the baby's sleep in time, which may easily lead to accidents. [0003] At present, there are also many technologies used in the monitoring of infant sleep. The invention patent w...

AI Technical Summary

Problems solved by technology

The defect of this product is: the strap restricts the activity of the baby, thereby causing the baby's discomfort, and does not have the function of connecting with the mobile terminal, so the guardian cannot grasp the baby's real-time sleep status, because the alarm device is placed on the strap , it is difficult to hear the alarm if the guardian is not with the baby

The disadvantages of this device are: uncomfortable to wear and inconvenient to clean

The disadvantages of this system are: the structure is too complicated, multiple sensors need to be installed in the mattress, which increases the assembly cost, and the function is not comprehensive. If the baby has weak breathing, its piezoelectric sensor and temperature sensor are difficult to detect

The defect of this product is: the respiratory rate detection device placed in the baby clothing includes two metal plates, a displacement curve drawing device, a counter and a capacitance detector. There are many parts, which will cause discomfort and inconvenience to the baby, and even affect the baby's normal sleep, and the capacitive detector used is susceptible to electromagnetic interference from the environment
