“…The sensor technologies include thermal, humidity, acoustic, pressure, resistive, inductive, acceleration, electromyography, and impedance. A wearable device with these sensors can be mounted into chest belts, attached to a chest belt [40][41][42][43], or applied to the skin [44,45], amongst other modes of attachment.…”

“…The sensor can be a nasal or oronasal thermistor, humidity sensor or a CO2 sensor which detects the temperature/humidity/CO2 changes between the inhaled and exhaled air. 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].…”

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.

Electronic skin made of thin, soft, stretchable devices that can mimic the human skin and reconstruct the tactile sensation and perception offers great opportunities for prosthesis sensing, robotics controlling, and human-machine interfaces. Advanced materials and mechanics engineering of thin film devices has proven to be an efficient route to enable and enhance flexibility and stretchability of various electronic skins; however, the density of devices is still low owing to the limitation in existing fabrication techniques. Here, we report a high-throughput one-step process to fabricate large tactile sensing arrays with a sensor density of 25 sensors/cm2 for electronic skin, where the sensors are based on intrinsically stretchable piezoelectric lead zirconate titanate (PZT) elastomer. The PZT elastomer sensor arrays with great uniformity and passive-driven manner enable high-resolution tactile sensing, simplify the data acquisition process, and lower the manufacturing cost. The high-throughput fabrication process provides a general platform for integrating intrinsically stretchable materials into large area, high device density soft electronics for the next-generation electronic skin.

Human respiration is an indispensable physiological behavior of the body, which is an important indicator to evaluate health status, especially for sleep‐related diseases. A real‐time respiratory monitoring and sleep breathing detecting system with convenience, high sensitivity, simple fabrication, and wearing comfort still remains a challenge and urgently desirable. Here, a breathable, highly sensitive, and self‐powered electronic skin (e‐skin) based on a triboelectric nanogenerator (TENG) is reported for real‐time respiratory monitoring and obstructive sleep apnea‐hypopnea syndrome (OSAHS) diagnosis. By using multilayer polyacrylonitrile and “polyamide 66” nanofibers as the contact pairs, and deposited gold as the electrodes, a contact‐separation type of TENG‐based all‐nanofiber e‐skin is developed. The e‐skin has a peak power density of 330 mW m−2, high pressure sensitivity of 0.217 kPa−1, excellent working stability, and good air permeability. Therefore, the e‐skin is simultaneously capable of energy autonomy and accurate real‐time subtle respiration monitoring. Meanwhile, a self‐powered diagnostic system for real‐time detection and severity evaluation of obstructive sleep apnea‐hypopnea syndrome are further developed to prevent the occurrence of OSAHS, delay its development, and improve sleep quality. This study hopes to pave a new and practical pathway for real‐time respiration monitoring and sleep breathing diseases clinical detection.
