Miniaturized Battery-Free Wireless Systems for Wearable Pulse Oximetry.
This engineering study describes miniaturized, flexible, battery-free wearable pulse oximetry systems that use near-field communication (NFC) for wireless operation. The devices capture and transmit photoplethysmograms to derive blood oxygenation, heart rate, and heart rate variability. The abstract reports demonstrations across body locations and quantitative comparisons to clinical gold standards supporting measurement accuracy, alongside investigations of RF and interface-material considerations.
