    Abstract: Pulse oximeter devices include a first light emitting element that emits red light, a second light emitting element that emits green light or IR light; and a sensor element that detects red and green (or IR) light and that outputs signals representing detected red and green (or IR) light. The pulse oximeter device further includes a flexible substrate, wherein the first light emitting element, the second light emitting element and the sensor element are formed on the flexible substrate. The sensor element is configured to detect the emitted red and green light transmitted through tissue containing blood, and in certain aspects, the sensor element is configured to detect the emitted red and green (or IR) light reflected by tissue containing blood. A signal processing element (e.g., a processor) receives and processes the signals representing detected red and green (or IR) light output by the sensor element to produce signals representing blood oxygenation content.

    IPC: A61B5/1455

    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.
