“…Mendelson et al investigated a multichannel reflectance pulse oximeter that proved to be efficient for robust noise cancellation with PPG signal acquired concurrently from each channel [29]. Chacon et al reported a wireless wearable pulse oximeter that was integrated with a novel data-dependent motion artefact tailoring algorithm, which demonstrated to be an efficient method for continuous monitoring of SpO2 [30]. Another recent study by Harvey et al developed an algorithm based on the time-frequency components of a PPG, which was demonstrated to have an accuracy of 96.76% for SpO2 measurements with motion artefacts and at low oxygen level [31].…”

Coronavirus disease 2019 (COVID-19) has emerged as a pandemic with serious clinical manifestations including death.A pandemic at the large-scale like COVID-19 places extraordinary demands on the world's health systems, dramatically devastates vulnerable populations, and critically threatens the global communities in an unprecedented way. While tremendous efforts at the frontline are placed on detecting the virus, providing treatments and developing vaccines, it is also critically important to examine the technologies and systems for tackling disease emergence, arresting its spread and especially the strategy for diseases prevention. The objective of this article is to review enabling technologies and systems with various application scenarios for handling the COVID-19 crisis. The article will focus specifically on 1) wearable devices suitable for monitoring the populations at risk and those in quarantine, both for evaluating the health status of caregivers and management personnel, and for facilitating triage processes for admission to hospitals; 2) unobtrusive sensing systems for detecting the disease and for monitoring patients with relatively mild symptoms whose clinical situation could suddenly worsen in improvised hospitals; and 3) telehealth technologies for the remote monitoring and diagnosis of COVID-19 and related diseases. Finally, further challenges and opportunities for future directions of development are highlighted.

“…Another issue related to poor perfusion is that SpO 2 readings from finger-tip pulse oximetry change with limb temperature, particularly if the fingers and hands are too cold [33]. Motion artifacts from movement, a widely studied problem, can cause false readings and interrupt continuous measurements [34]- [36]. One major issue involves the presence of carboxyhemoglobin and methemoglobin, such as in carbon monoxide poisoning and methemoglobinemia.…”

“…Not surprisingly, the wearable fitness technology market was valued at $5.77 billion in 2016 and it is expected to be worth $12.44 billion by 2022, growing at an estimated compound annual growth rate (CAGR) of 13.7% from 2016 to 2022 [3]. Among the different physiological parameters of interest, we must highlight the monitoring of heart rate [4], blood pressure [5,6], respiration rate [7], body temperature [8] and sweat [9][10][11][12]. In contrast with traditional health monitoring instruments, wearable devices have some key advantages such as portability, ubiquity or ease of use, and they are able to provide continuous, real-time, wireless monitoring of health conditions in a noninvasive way [13][14][15][16].…”

Several studies have shown that the determination of pH in sweat, which is one of the most accessible body fluids, can be an indicator of health and wellness, and even be used for potential disease diagnosis. On that basis, we present herein a wearable wristband for continuous and wireless monitoring of sweat pH with potential applications in the field of personal health assessment. The developed wristband consists of two main parts: a microfluidic cloth analytical device (μCAD) to collect continuously the sweat from skin with a color-based pH sensing area; and a readout and processing module with a digital color sensor to obtain the pH of sweat from the color changes in the μCAD. In addition, the readout module includes a low-power Bluetooth interface to transmit the measurements in real-time to a custom-designed smartphone application. To allow continuous operation, an absorbent pad was included in the design to retire and store the sweat from the sensing area through a passive pump path. It was found that the Hue parameter (H) in the HSV color space can be related to the sweat pH and fitted to a Boltzmann equation (R 2 =0.997). The range of use of the wristband device goes from 6 to 8, which includes the pH range of sweat, with a precision at different pH values from 3.6 to 6.0 %. Considering the typical human sweat rate, the absorbent pad allows continuous operation up to more than 1000 minutes.
