_{PPG is a non-invasive device that measures the volumetric variations of blood circulation by using a light source and a photodetector at the skin’s surface. Remote PPG (rPPG) is a PPG technological progression that does not require physical touch, instead relying on ambient light reflected from the skin and collected remotely by a CMOS (complementary metal-oxide semiconductor) camera. The collected color signals can then be filtered using AI techniques like Independent Component Analysis (ICA).}

_{When a patient stares at a tablet or smartphone, the camera detects changes in the skin by reflecting light off blood vessels in the hypodermis. The camera’s data are then transformed into red, green, and blue (RGB) values and transmitted to the cloud at a rate of 30 times per second.}

_{These RGB data are then subjected to independent component analysis, signal processing, and Caare’s algorithms before being returned as vital signs readings.}

_{Caare offers a single set of measurements—currently necessitated by many devices—in under 40 seconds.}

_{With Caare’s technology, patients and consumers may have their non-contact static health monitored without the use of extra equipment thanks to the widespread use of mobile phones and tablets.}
