The video captured when you unlock your phone with your face might also be able to monitor your heart rate, according to international research. The study used over 190,000 videos to develop the system, which uses video to measure blood flow.

The researchers say the results highlight the potential of smartphones for enabling passive and equitable monitoring of heart health.
