New Smartphone Method Measures Heart Rate During Device Unlocking

Researchers have developed a new method that allows smartphones to measure a user’s heart rate during the standard device-unlocking process. This technology utilizes existing smartphone sensors to capture physiological data, potentially expanding health monitoring capabilities to billions of users without the need for additional wearable hardware.

The process functions by leveraging the sensors already integrated into modern mobile devices to detect subtle changes in the user’s physical state as they interact with their phone. While wearable devices like smartwatches and fitness trackers currently provide continuous health data—including blood oxygen levels, sleep quality, and heart rate—this new approach integrates similar monitoring functions directly into the smartphone interface. By utilizing the hardware already present in most handsets, this development aims to make personal health tracking more accessible to a broader global population.
