Skin‐Integrated Wearable Electronics: A Dual‐Interface Perspective
SmartSys, Volume 1, Issue 4, December 2025.ABSTRACT Skin‐integrated wearable electronics enable continuous, medical‐grade monitoring and therapy in daily life, but must balance conflicting needs related to mechanics, power, and communication. This review uses a dual‐interface approach that separates the sensor–receiver interface, which handles wireless data and energy transfer, from the sensor ...

Toward Generating More Diagnostic Features from Photoplethysmogram Waveforms
Diseases, 2018 Photoplethysmogram (PPG) signals collected using a pulse oximeter are increasingly being used for screening and diagnosis purposes. Because of the non-invasive, cost-effective, and easy-to-use nature of the pulse oximeter, clinicians and biomedical engineers are investigating how PPG signals can help in the management of many medical conditions ...
