May enhance wearable cuffless BP monitoring; leaves open clinical validation before practice adoption.
Absolute Event Rate: 8.02% vs 6.74%
A newly designed PPG module with optimized LED/PD distances achieved higher signal quality and accurate blood pressure measurements meeting established standards.
Kao et al. (2018) studied Blood pressure sensing. New optimized PPG module vs. Commercial PPG modules was evaluated on ac/dc ratio of PPG signals. A newly designed PPG module achieved an ac/dc ratio of 8.02% compared to 6.74% and 6.90% for commercial modules, yielding high accuracy for blood pressure sensing.
