Samsung’s folding screen gadget may have an under-screen blood pressure sensor

Manufacturers of smartphones have started to investigate the introduction of more fitness sensors in recent years. A blood pressure monitoring software for folding screen devices is described in the latest Samsung patent mentioned in this article. Samsung Electronics filed a patent application entitled “Methods for Estimating Biological Information Using Foldable Electronic Devices” to the United States Patent and Trademark Office (USPTO) in April 2020, which was officially revealed to the outside world on March 25, 2021, according to the Dutch technology blog LetsGoDigital.

This biosensor detection approach under the flexible screen, according to the document’s diagram, can be used for in-folding tablet/folding screen smart phones like the Galaxy Z Flip and Galaxy Z Fold 2.

The machine transforms the pixel pressure into the pulsation amplitude by putting the index finger on the folding screen sensor to collect image data, and then analyzes and displays related health information.

This program, according to Samsung, can also be used to assess vascular age, aortic pressure waveform, vascular compliance, pressure index, and fatigue index in addition to blood pressure.

Samsung has also proposed mounting the sensor on the outside of the smartphone and weighing it by attaching it to the palm of the hand as an option. Alternatively, squeeze the sensors at the screen’s edge on both sides at the same time to correctly measure the pulse signal’s propagation time (PTT) and output the blood pressure frequency.

Samsung also hopes to understand the user’s gender, weight, and BMI index, as well as the temperature and humidity of the measurement area, at the software level, in order to increase measurement precision. Then, using a predefined model, they can collect updates on their fitness.

While it is unclear if Samsung will have this feature in its own folding screen products in the coming years, the Galaxy Z Flip 3 and Galaxy Z Fold 3, all of which have standardized digital names, are expected to be released in July 2021.
