This research area focuses on developing watchband-based wearable platforms for continuous, noninvasive blood pressure monitoring using advanced arterial pressure-wave sensing techniques. These systems are designed to enable cuffless blood pressure estimation under both static and dynamic conditions, supporting long-term cardiovascular monitoring outside traditional clinical environments.
The technology integrates novel mechanical sensing architectures that directly capture pressure-wave morphology through the skin, providing improved physiological fidelity compared to conventional optical-only wearable approaches. Multimodal sensing capabilities enable the integration of complementary measurements, including photoplethysmography (PPG), electrocardiography (ECG), skin temperature, motion sensing, and biochemical sensing modalities.
Research efforts span wearable device architecture, human-subject validation, development of physiologically realistic phantoms, embedded electronics design, signal processing, and machine-learning-based physiological modeling. The long-term objective is to enable clinically actionable continuous cardiovascular monitoring using scalable, comfortable, and robust wearable platforms suitable for ambulatory, operational, and at-home healthcare settings.
