Blood oxygen saturation (SpO 2 ) measurement is a routinely performed clinical procedure involved in the diagnosis of several critical diseases. However, the most commonly used SpO 2 measuring device, known as oximeter, becomes unreliable in the absence of proper body contact. A non-contact, noninva...
