TL;DR: Theoretical analyses of system-level bending mechanics show the advantages of WiSP’s flexible electronics, soft encapsulation layers and bioadhesives, enabling intimate skin coupling, and its physical attributes and performance results demonstrate its utility for monitoring cardiac signals during daily activity, exertion and sleep.
Journal ArticleDOI
Current progress of photoplethysmography and SPO2 for health monitoring.
TL;DR: The principle issues and clinical applications of PPG for monitoring oxygen saturation are reviewed and wearable unobtrusive PPG monitors are commercially available.

TL;DR: It is concluded that the ear is relatively immune to the vasoconstrictive effects of the cold pressor test, and the comparison of the ear and finger pulse oximeter wave forms might be used as a real-time monitor of sympathetic tone and the ear plethysmography may be a suitable monitor of the systemic circulation.

Ambient and Unobtrusive Cardiorespiratory Monitoring Techniques
TL;DR: This review provides a systematic and comprehensive review over the current state of the field of ambient and unobtrusive cardiorespiratory monitoring and systematically analyzes similarities and differences between these methods with respect to the physiological and physical effects they sense as well as the resulting implications.
Journal ArticleDOI

Aymen A. Awad,Ala S. Haddadin,Hossam Tantawy,Tarek M. Badr,Robert G. Stout,David G. Silverman,Kirk H. Shelley +6 more
TL;DR: Pulse width of finger and ear plethysmographic tracing are more sensitive to changes in SVR than the other indices, suggesting an appreciation of changes in pulse width may provide valuable evidence with respect toChanges in peripheral vascular tone.
