Project
RP4: Aqu. ammonia, aqu. urea and nitrate monitoring sensors (ESR4, UoG)
Ammonium, nitrate and urea are often observed in field water samples due to many chemical fertilizers. The measurement of these analytes provides information on metabolic processes of water bodies. The concentration of NO3− and NH4+is the major factor which control the level of inorganic nitrogen species. Fertilizers, high temperature combustion sources and sewage, lead to increased concentration of these analytes and therefore monitoring these parameters in water is important for better aquatic life. To monitor, these parameters over a low to high concentration range, highly sensitive nanostructured material based sensors will be developed in this project.
RP6: Pressure and turbidity sensors (ESR 6, UoG)
There could be significant variation in the response of sensors during water quality monitoring as water pressure, slit and mud etc. affect the performance and post calibration challenges. To address this issue, this project will develop pressure and turbidity sensors and integrate them on multi-sensors patch. The interdigitated graphene based highly-sensitive capacitive pressure sensors will be developed on flexible substrate such as PET. The turbidity sensors will be fabricated by using 3D printed packages. The integration of turbidity sensors in the proposed multi-sensors, is advantageous in terms of predicting the selectivity and also for deployment of sensors.
RP9: 3D printing methodologies for sensor system packaging (ESR9, FBK)
In many applications and research activities involving micro/nanosensors, the packaging issues have been often underestimated by compromising important features as sensors sensitivity, reproducibility and throughput. The integration of multisensory systems on robots or buoys will require advanced packaging strategies. Recent advances in 3D printing have demonstrated the possibility to creating packages with polymers, metals, composites and ceramics, which have higher adaptability to different environmental conditions. 3D printing enables the creation of complex geometric shapes and merging of selected functional components into any configuration, thus supplying a new approach for the fabrication of multifunctional end-use devices that can potentially combine optical, chemical, electronic, electromagnetic, fluidic, thermal and acoustic features. Starting from this premise, ESR9 will: (1) model, design and create multi-process 3D printing methodologies; (2) suggest 3D printing architectures for more sophisticated devices with a higher level of automation and increased integration/packaging level; (3) develop packages to integrates the sensory system developed by other ESRs in AQUASENSE.
