Low-Rate Wrist SpO2 Estimation under Micro-Perturbations Using Motion-Aware Beat Selection and Perfusion-Guided Calibration
A lightweight low-rate wrist SPO2 estimation framework that integrates motion-aware beat selection and perfusion-guided calibration is proposed that achieves the best 25 Hz performance and reduces PPG sensor power consumption for energy-efficient wearable implementation.
