“…developed a smart mask consisting of a self‐powered pressure sensor via electrostatic (triboelectric) effect. [ 277 ] The sensor has the advantages of miniaturization (2.5 × 2.5 cm 2 ), light weight (4.5 mg), and can output a peak voltage of up to 10 V during airflow stimulation. By wearing the mask as shown in Figure 6c, wireless monitoring of various breathing conditions such as normal breathing, shortness of breath, coughing, and breath‐holding can be realized, promising to record and analyze personal respiratory‐related diseases.…”

Wearables and bioelectronics rely on breathable interface devices with bioaffinity, biocompatibility, and smart functionality for interactions between beings and things and the surrounding environment. Elastic fibers/fabrics with mechanical adaptivity to various deformations and complex substrates, are promising to act as fillers, carriers, substrates, dressings, and scaffolds in the construction of biointerfaces for the human body, skins, organs, and plants, realizing functions such as energy exchange, sensing, perception, augmented virtuality, health monitoring, disease diagnosis, and intervention therapy. This review summarizes and highlights the latest breakthroughs of elastic fibers/fabrics for wearables and bioelectronics, aiming to offer insights into elasticity mechanisms, production methods, and electrical components integration strategies with fibers/fabrics, presenting a profile of elastic fibers/fabrics for energy management, sensors, e‐skins, thermal management, personal protection, wound healing, biosensing, and drug delivery. The trans‐disciplinary application of elastic fibers/fabrics from wearables to biomedicine provides important inspiration for technology transplantation and function integration to adapt different application systems. As a discussion platform, here the main challenges and possible solutions in the field are proposed, hopefully can provide guidance for promoting the development of elastic e‐textiles in consideration of the trade‐off between mechanical/electrical performance, industrial‐scale production, diverse environmental adaptivity, and multiscenario on‐spot applications.

“…Several respiration‐sensing devices for the static monitoring of human respiration signals have been developed, [ 12–15 ] including triboelectric and resistive sensors for identifying respiration rates before and after physical exercise. Unfortunately, existing devices are far from portable, compact and smart enough, and do not meet the needs for efficient signal collection and processing in complex environments such as frequent moving in daily interactions, [ 16–18 ] without restricting the user's freedom.…”

Respiration signals reflect many underlying health conditions, including cardiopulmonary functions, autonomic disorders and respiratory distress, therefore continuous measurement of respiration is needed in various cases. Unfortunately, there is still a lack of effective portable electronic devices that meet the demands for medical and daily respiration monitoring. This work showcases a soft, wireless, and non‐invasive device for quantitative and real‐time evaluation of human respiration. This device simultaneously captures respiration and temperature signatures using customized capacitive and resistive sensors, encapsulated by a breathable layer, and does not limit the user's daily life. Further a machine learning‐based respiration classification algorithm with a set of carefully studied features as inputs is proposed and it is deployed into mobile clients. The body status of users, such as being quiet, active and coughing, can be accurately recognized by the algorithm and displayed on clients. Moreover, multiple devices can be linked to a server network to monitor a group of users and provide each user with the statistical duration of physiological activities, coughing alerts, and body health advice. With these devices, individual and group respiratory health status can be quantitatively collected, analyzed, and stored for daily physiological signal detections as well as medical assistance.
