Summary:In an example, a method to monitor blood pressure of a subject includes: generating a first signal representing cardiac electrical activity of the subject using a first sensor of a wearable system; generating a second signal representing cardiac photonic activity of the subject using a second sensor of the wearable system; generating a third signal representing cardiac mechanical activity of the subject using a third sensor of the wearable system; determining from the third signal a time period during which the first and second signals are likely clean; extracting one or more features from portions of two or more of the first, second, or third signals corresponding to the time period, the one or more extracted features including at least one of a PTT, a PAT, or BVE features; and determining a current blood pressure of the subject based on the one or more extracted features.
