“…A common form of ACT is a bracelet or watch worn on a part of the body, with less contact with the human body; besides, the non‐contact mattress sleep monitoring system had been successfully developed and used 160 ; thus, it is unlikely that ACT substantially influence normal sleep. A traditional ECG monitoring method involves placing electrode patches on chest, which can cause discomfort, but great strides have been made in the development of non‐contact ECG monitoring methods 253,254 . Generally, ECG is less disruptive than the sensors applied for polysomnography, and it is unlikely that the ECG alone substantially influences normal sleep.…”

To date, although many studies had focused on the impact of environmental factors on sleep, how to choose the proper assessment method for objective sleep quality was often ignored, especially for healthy subjects in bedroom environment. In order to provide methodological guidance for future research, this paper reviewed the assessments of objective sleep quality applied in environmental researches, compared them from the perspective of accuracy and interference, and statistically analyzed the impact of experimental type and subjects' information on method selection. The review results showed that, in contrast to polysomnography (PSG), the accuracy of actigraphy (ACT), respiratory monitoring‐oxygen saturation monitoring (RM‐OSM), and electrocardiograph (ECG) could reach up to 97%, 80.38%, and 79.95%, respectively. In terms of sleep staging, PSG and ECG performed the best, ACT the second, and RM‐OSM the worst; as compared to single methods, mix methods were more accurate and better at sleep staging. PSG interfered with sleep a great deal, while ECG and ACT could be non‐contact, and thus, the least interference with sleep was present. The type of experiment significantly influenced the choice of assessment method (p < 0.001), 85.3% of researchers chose PSG in laboratory study while 82.5% ACT in field study; moreover, PSG was often used in a relatively small number of young subjects, while ACT had a wide applicable population. In general, researchers need to pay more attention at selection of assessments in future studies, and this review can be used as a reliable reference for experimental design.

“…[ 10 ] While FPS holds potential for physiological data tracking, their application in inconspicuous BCG signal monitoring remains unexplored. [ 11 ] To date, the FPSs developed for BCG monitoring predominantly rely on piezoelectric [ 12 ] or triboelectric mechanism, [ 13 ] which are well‐suited for dynamic monitoring. However, these mechanisms may have limitations when it comes to the long‐term monitoring of static responses.…”

Long‐term surveillance records of cardiac activity are essential for people at potential risk of cardiovascular disease. However, the existing mainstream technologies for cardiac monitoring, such as electrocardiography (ECG) and photoplethysmography (PPG), are inconvenient and prone to skin allergies due to contact measurements. Ballistocardiography (BCG) is a vibration signal related to cardiac activity, which can be monitored in an unconstrained way. Herein, an iontronic textile‐type flexible capacitive pressure sensor (i‐TFCPS) based on ionic liquid doped hollow‐porous fiber is developed to monitor physiological signals. With a high sensitivity of 7.26 kPa−1, a wide pressure range (10 Pa–600 kPa), a fast response time of 30 ms, and decent durability over 3500 cycles, the i‐TFCPS is simultaneously capable of detecting and tracking the static and dynamic changes of sitting posture, and subtle physiological information, such as respiration and BCG signals. Benefits from the iontronic textile as sensitive dielectric, the capacitive pressure sensor is able to monitor the subtle BCG signal under high static pressure in an unconstrained state, showing great potential for unobtrusive cardiac monitoring in home, office and hospital.
