The Korean giant really wants to take care of us!
A freshly published patent application reveals that Samsung devices could integrate a contactless system to detect biological parameters, such as blood pressure, heart rate, blood oxygen saturation, blood vessel elasticity, blood flow rate, and arterial stiffness.
But how it works? It seems that by using light emitting diods (LEDs) and/or laser diods (LDs), and a set of photodetectors arranged in 2D arrays, such biological parameters can be detected and analyzed. For example, the movement of the skin surface due to contraction and relaxation of a blood vessel can be detected and related to biological
information. In other words, you could simply place a smartphone near your wrist, and get the blood pressure. Impressive!
The patent application for this technology is currently under review.
