FULLY INTEGRATED OXYGEN SENSOR WITH FOUR LAYER PRINTED CIRCUIT ELECTRONICS ON PAPER

Paper-based devices are receiving significant attention for low-cost disposable medical diagnostics in resource-poor settings. However one still needs to interface paper based diagnostic devices with external readout units that are sometimes bulky and expensive, which makes them less suitable for wearable and disposable applications. In this paper we report a novel miniaturized and low cost integrated sensor platform on paper substrates for monitoring wound oxygenation, one of the critical parameters in wound healing. The device also contains a 4-layer multi-purpose printed circuit board (PCB) integrated along with sensor on the same paper substrate.
