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.

Abstract: Methods for simultaneously forming two or more different colored material layers on a substrate. include performing surface energy patterning (SEP) to define a first, hydrophobic region and a second, hydrophilic region on the substrate, applying first and second materials on the second region, wherein the first material comprises a material having a first color, and wherein the second material comprises a material having a second color, and doctor blade coating the first and second materials simultaneously to form first and second material layers on the substrate. The methods are particularly useful for making multi-color light emitting and detecting components such as LEDs and OPDs.

Abstract: NIRS systems including fully-printed LEDs and PDs operating in the NIR spectrum are provided that provide conformal adherence to a patient's head and efficient measurement of near-infrared absorption. Circuitry processes and wirelessly transmits data from one or multiple devices located on a patients head to a remote and/or portable device. Using multiple sensors improves the spatial resolution of the measurements, and post processing on the portable device provides the ability to transmit results to a patient's physician, e.g., via a secure internet connection.
