Owlet is using the same technology that is used in the hospital by doctors to make sure you are ok. It is called pulse oximetry it has been around for decades and it is that little red light they clip on your finger when you go to the hospital. It is also the same technology that is found on the new Apple Smartwatch. It simply uses small LED lights, shining them onto the skin and sensing how much light makes it back to the photo receptor. Pulse Oximetry is proven, safe and used all over the world.
