This project has two main objectives. The first objective is to take advantage of 3D printing techniques (developed by Professor Busnaina at Northeastern University) to print patterns of nanomaterials such as carbon nanotubes, graphene, and molybdenum disulfide to fabricate a suite of sensors with different nanomaterials and metal leads directly on a daughter board that can be wire bonded to a Printed Circuit Board (PCB). These sensors will then be tested with target gases. The second objective is to develop the Front End Electronics (FEE) to read out the sensors. Using the sensor response to target gases, the PI and team can then initiate development of algorithms for technology demonstration. This CIF will leverage previous internal research efforts, complete the FEE development, incorporate a plug-and- play interface for the nanosensors, and characterize them with gases (ammonia and hydrogen). Innovative aspects include the fabrication of nanosensors with 3D printing, and custom plug-and-play FEE and DSP techniques.
