Israeli startup lets users check vital signs by looking at their smartphones

Israeli startup Binah.ai says it has developed technology that turns smartphones into health monitoring devices that can check vital signs including heartrate, oxygen saturation and respiratory rate. The new technology comes as medical care worldwide has been stretched thin by the pandemic and other, longer-term trends, spurring demand for telemedicine and cheaper, more convenient health monitoring solutions. The user just needs to look into the camera to let the company's system measure their vital signs. Our skin is constantly undergoing rapid changes in color, too subtle for us to notice, that reflect our body's physical state and functioning. "Basically we're following around the tiny color changes that are happening to the skin and the tiny color changes indicate the blood flow that is happening below the skin surface," Maman said.
