Low-power ECG acquisition systems suitable for wearable applications are extensively reported in the literature, where techniques such as voltage scaling, compressed sampling, and duty-cycled transmission reduce overall power consumption. Heart rate serves as a primary vital sign to monitor cardiovascular health, and continuous hearbeat monitoring can detect pulse irregularities to diagnose underlying conditions conventionally, an electrocardiogram (ECG) is used. Also, long-term monitoring requires continuous, untethered power, difficult to obtain from portable batteries. However, medically relevant recording of vitals outside of the clinic is challenging: motion artifacts degrade signal quality and detection accuracy, demanding energy-intensive signal processing. WEARABLE devices can enable ambulatory measurement of human vital signs and continuous monitoring of physiological parameters, which may be valuable for chronic care and early diagnosis of disease.
