Future Samsung foldable phones could get some serious health tracking features
The pictures from the patent reveal two ways of measuring your health status. The first method will be by sticking your finger between the two parts of the folding screen when closed. Then, sensors will measure things like your blood pressure and heart rate.
Another way to measure your vitals will be to hold a clamshell type of phone opened in your palm. The phone will have its sensors on its back. For it to measure your vitals, you would need to put one end of the phone at your finger and the other on your palm, while staying static.
The new sensors will measure how blood flows through your finger by using an amplitude conversion method. The phone will sense your pulse wave amplitude via its sensors, which will take an image and then analyze the intensity of its pixels, and convert it to the desired measurement.
There are several other measurements that will apparently be possible with this design. We’ve already mentioned the blood pressure and heart rate capabilities of the sensors, but according to the patent, they will also measure other vitals like vascular age, vascular compliance, aortic pressure waveform, arterial stiffness, stress levels and fatigue levels.
It is unclear whether the new sensors will appear on the Galaxy Z Fold 3 and the Galaxy Z Flip 3.
