Wearable sensors and feedback system to improve breathing technique (original) (raw)

Breathing feedback system with wearable textile sensors

2010

Abstract Breathing exercises form an essential part of the treatment for respiratory illnesses such as cystic fibrosis. Ideally these exercises should be performed on a daily basis. This paper presents an interactive system using a wearable textile sensor to monitor breathing patterns. A graphical user interface provides visual real-time feedback to patients. The aim of the system is to encourage the correct performance of prescribed breathing exercises by monitoring the rate and the depth of breathing.

Wearable Spirometry : Using Integrated Environment Sensor for Breath Measurement

2018

In this work, we present and evaluate a concept for using an integrated environment sensor as a wearable spirometer. Unlike a standard spirometer that by design is fairly bulky, our device can be unobtrusively integrated into various configurations suitable for long-term use in everyday settings (open headset, regular face mask, and professional sports mask). The sensor measures the transient change in air pressure, humidity and temperature in front of wearers’ mouth and nostrils. We present our hardware design and signal analysis methods needed to extract breathing rate information. We compare the results with a standard spirometer. Moreover, a calibration between the BME280 sensor and the spirometer is performed, having both working in parallel. We show that our approach is able to distinguish between normal breaths and deep breaths, as well as to capture the period and magnitude of the breath cycles, with a wearable device that can be used in everyday scenarios, as well as sport ...

The Effect of Measurement Trends in Belt Breathing Sensors

Engineering Proceedings

Sensors for respiratory monitoring can be classified into wearable and non-wearable systems. Wearable sensors can be worn in several positions, the chest being one of the most effective. In this paper, we have studied the performance of a new piezoresistive breathing sensing system to be worn on the chest with a belt. One of the main problems of belt-attached sensing systems is that they present trends in measurements due to subject movements or differences in subject constitution. These trends affect sensor performance. To mitigate them, it is possible to post-process the data to remove trends in measurements, but relevant data from the respiration signal may be lost. In this study, two different detrending methods are applied to respiration signals. After conducting an experimental study with 21 subjects who breathed in different positions with a chest piezoresistive sensor attached to a belt, detrending method 2 proved to be better at improving the quality of respiration signals.

Wearable Biosensor: How to Improve the Efficacy in Data Transmission in Respiratory Monitoring System

International Journal of Electronics and Telecommunications, 2023

Respiratory rate measurement is important under different types of health issues. The need for technological developments for measuring respiratory rate has become imperative for healthcare professionals. The paper presents an approach to respiratory monitoring, with the aim to improve the accuracy and efficacy of the data monitored. We use multiple types of sensors on various locations on the body to continuously transmit real-time data, which is processed to calculate the respiration rate. Variations in the respiration rate will help us identify the current health condition of the patient also for diagnosis and further medical treatment. The software tools such as Keil µVision IDE, Mbed Studio IDE, Energia IDE are used to compile and build the system architecture and display information. EasyEDA is used to provide pin map details and complete architecture information.
