CRHE-Long-Term-PPG-BP-Dataset

The CRHE dataset is a publicly available, multi-wavelength, dual-24h photoplethysmography (PPG) and blood pressure (BP) dataset, collected using wearable devices and ambulatory BP monitors. It contains synchronized PPG signals and reference BP measurements from subjects over two separate 24-hour periods, enabling the study of circadian rhythm effects on BP. In addition to high-quality signal recordings, CRHE features detailed circadian rhythm annotations and supports research on continuous, cuffless BP estimation and physiological monitoring. By providing CRHE, we aim to advance the development and benchmarking of intelligent BP and circadian rhythm monitoring in healthcare IoT systems.
