Solution Processed Flexible Near-Infrared Organic Light Emitting Diodes And Organic Photodetectors for Wearable Sensors

Solution processed near-infrared (NIR) organic light emitting diodes and NIR absorbing organic photodetectors are physically flexibile, manufacturable with low cost roll-to-roll processes, and scalable to large areas and volumes. These characteristics make them attractive candidates for wearable sensors. Inorganic NIR emitters and detectors have recently been used in medical and imaging applications, but have been limited by their lack of ‘wearability’ due to inflexibility and high scaling costs. When interfaced with standard inorganic electronics for control, data processing, and data transmission, arrays of flexible organic NIR emitters and detectors will enable further development of new medical diagnostic techniques and therapies and personal security verification.
