Abstract

Background

Monitoring COVID-19 symptoms has become a critical task in controlling the spread of the virus and preventing hospitalizations. Aiming to contribute to efficient monitoring solutions, this article presents the development and testing of a wearable device capable of continuous monitoring biometric signals associated with the presence of COVID-19, such as the heart rate, the blood oxygen saturation, and the body temperature.

Methods

To ensure continuous monitoring the device is designed to be worn in the ear. Here, the temperature is measured through a non-contact infrared temperature sensor placed inside the ear canal while the heart rate and the pulse oximetry signals are monitored through a photoplethysmography reflective sensor positioned at the earlobe.

The proposed device's performance was evaluated by comparing it against a medical certified station. Usability and ergonomics were assessed through users' questionnaires. Additionally, experiments were performed to evaluate the hearing loss when the proposed device is in use. Data was acquired from 30 individuals of different sex, aged between 20 and 43 years old. In relation to usability and ergonomics the variation in ear dimensions was accessed and related to the device's comfort limitations.

Results

The temperature measurement produced a moderate correlation (R=0.42), despite a higher standard deviation was found in the proposed solution. This is due to the limited variability in temperature data, creating a short measuring range, as only healthy people were tested. The heart rate measurement also showed good correlation (R=0.96), with the proposed solution showing good repeatability with a standard deviation of 6.06 BPM, however, the SpO2 measurement was suboptimal (R=0.14).

The ergonomic evaluation revealed that most participants found the device shape comfortable, but some found the dimensions not adequate.

Additionally, the device was found to be user-friendly, with most participants reporting that they found it to be intuitive, and none reported a major loss in hearing in a normal conversation, however, there's a negligible loss of approximately 0.56 dB.

Conclusions

During this study, it was possible to develop and evaluate a wearable device that was suggested for monitoring biometric signals. The device demonstrated great reliability in temperature and heart rate measurement but showed limitations in the accuracy of pulse oximetry. The main contribution of this work is the evaluation of a continuous non-invasive monitoring concept for COVID-19 related biometric signals, which indicates good applicability in the case study.

一种新型冠状病毒生物特征症状检测可穿戴式监测设备
监测COVID-19症状已成为控制病毒传播和预防住院治疗的关键任务。为了提供高效的监测解决方案,本文介绍了一种可穿戴设备的开发和测试,该设备能够连续监测与COVID-19存在相关的生物特征信号,如心率、血氧饱和度和体温。方法采用耳戴式装置,确保连续监测。在这里,温度是通过放置在耳道内的非接触式红外温度传感器测量的,而心率和脉搏血氧测量信号是通过放置在耳垂的光电容积脉搏波反射传感器监测的。通过与医疗认证站进行比较,评估了拟议设备的性能。通过用户问卷对可用性和人机工程学进行评估。此外,还进行了实验来评估所建议的设备在使用时的听力损失。数据来自30个不同性别的个体,年龄在20到43岁之间。在可用性和人体工程学方面,耳朵尺寸的变化与设备的舒适限制有关。结果温度测量产生中等相关性(R=0.42),尽管在提出的解决方案中发现较高的标准偏差。这是由于温度数据的变化有限,测量范围很短,因为只有健康的人被测试。心率测量也显示出良好的相关性(R=0.96),所提出的解决方案具有良好的重复性,标准偏差为6.06 BPM,但SpO2测量不理想(R=0.14)。人体工程学评估显示,大多数参与者认为设备形状舒适,但有些人认为尺寸不够。此外,该设备被发现是用户友好的,大多数参与者报告说他们发现它很直观,没有人报告说在正常对话中听力有重大损失,然而,大约0.56 dB的损失可以忽略。在这项研究中,有可能开发和评估一种可穿戴设备,该设备被建议用于监测生物特征信号。该装置在温度和心率测量方面表现出很高的可靠性,但在脉搏血氧测量的准确性方面存在局限性。本工作的主要贡献是对COVID-19相关生物特征信号的连续无创监测概念进行了评估,表明其在案例研究中具有良好的适用性。
