Amazon Alexa could monitor your heartbeat without even touching you ‘using invisible sound waves’

YOUR smart speaker could one day monitor your heartbeat as you go about your daily business at home.

US scientists have been working on a smart speaker system that could give your Amazon Alexa or Google Home the ability to spot irregular heartbeats.

Smart speakers could become contactless heart rate monitors with the AI-powered system.

Researchers designed a prototype that sends out sound waves we can’t hear to a person sitting nearby.

The waves bounce back off the person and are picked up by a sensor within the device that uses an algorithm to analyse them and count the time between heartbeats.

University of Washington researchers tested their device on healthy people and cardiac patients who were in hospital at the time.
