Abstract

A flexible oximeter device for measuring pulse and blood oxygen saturation in tissue includes a first array of first light emitting elements that emit red light, a second array of second light emitting elements that emit green light or near-infrared (NIR) light and an array of sensor elements arranged on at least one flexible substrate. Each sensor element is configured to detect red and green or NIR light, and to output a signal representing an amount of red or green or NIR light detected. The first and second arrays and the array of sensor elements form a plurality of interleaved measurement pixels, each pixel comprising one of the first light emitting elements and a corresponding sensor element, and one of the second light emitting elements and a different corresponding sensor element.
