Proof-of-concept system turns smart speakers into contactless heart rhythm monitors

Smart speakers such as the Amazon Echo or the Google Nest can be used to monitor heart rhythms without physical contact as effectively as an electrocardiogram, according to research from the University of Washington published in Communications Biology. The researchers created a proof-of-concept system where their self-supervised machine learning algorithm can turn smart speakers into short-range sonar devices that measures heart rate and inter-beat intervals for both regular.
