“…For example, Liu et al devised a flexible epidermal respiratory sensor based on the thermal convection effect which had high thermal sensitivity and could well capture various breathing patterns via mounting the sensor above the upper lip [45]. Dai et al developed a polyelectrolyte humidity sensor that can be integrated into a facial mask, as is widely used during the current pandemic [46]. But monitoring with a face mask can still be intrusive to users, and the displacement of the sensor may affect the accuracy.…”

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.

“…In general, high‐performance humidity sensors require sensing materials with large specific surface area and excellent intrinsic properties, which requires that the active material can interact with water molecules in short response time and result in great changes in certain properties. Based on this, a variety of new materials (eg, carbon dots, CNTs, graphene, transition metal dichalcogenides hydrogels, and polyelectrolytes) have been explored to improve the sensing performance of humidity sensors. Low‐dimensional material‐based humidity sensors are expected to have high sensitivity and fast response time due to the exposure of most of their atoms to the surface.…”

Skin, the largest organ in the human body, is sensitive to external stimuli.In recent years, an increasing number of skin-inspired electronics, including wearable electronics, implantable electronics, and electronic skin, have been developed because of their broad applications in healthcare and robotics.Physical sensors are one of the key building blocks of skin-inspired electronics. Typical physical sensors include mechanical sensors, temperature sensors, humidity sensors, electrophysiological sensors, and so on. In this review, we systematically review the latest advances of skin-inspired mechanical sensors, temperature sensors, and humidity sensors. The working mechanisms, key materials, device structures, and performance of various physical sensors are summarized and discussed in detail. Their applications in health monitoring, human disease diagnosis and treatment, and intelligent robots are reviewed. In addition, several novel properties of skin-inspired physical sensors such as versatility, self-healability, and implantability are introduced. Finally, the existing challenges and future perspectives of physical sensors for practical applications are discussed and proposed.

“…For instance, Liu et al [ 31 ] proposed a RR system that is used to be placed on the upper lip which is mainly a flexible epidermal respiratory system based on the thermal convection. Dai et al [ 32 ] introduced a polyelectrolyte humidity sensor, a particular type of humidity sensor that can be attached to a facial mask which is widely used during the COVID-19 pandemic. But the system may not be suitable for the patients and the movement of the sensor may influence the accuracy.…”

Wearable technology plays a significant role in our daily life as well as in the healthcare industry. The recent coronavirus pandemic has taken the world’s healthcare systems by surprise. Although trials of possible vaccines are underway, it would take a long time before the vaccines are permitted for public use. Most of the government efforts are currently geared towards preventing the spread of the coronavirus and predicting probable hot zones. The essential and healthcare workers are the most vulnerable towards coronavirus infections due to their required proximity to potential coronavirus patients. Wearable technology can potentially assist in these regards by providing real-time remote monitoring, symptoms prediction, contact tracing, etc. The goal of this paper is to discuss the different existing wearable monitoring devices (respiration rate, heart rate, temperature, and oxygen saturation) and respiratory support systems (ventilators, CPAP devices, and oxygen therapy) which are frequently used to assist the coronavirus affected people. The devices are described based on the services they provide, their working procedures as well as comparative analysis of their merits and demerits with cost. A comparative discussion with probable future trends is also drawn to select the best technology for COVID-19 infected patients. It is envisaged that wearable technology is only capable of providing initial treatment that can reduce the spread of this pandemic.
