Sustainable autonomous system for nitrites/nitrates and heavy metals monitoring of natural water sources - WaterSafe

Project summary

The project sets to develop a new energy autonomous system based on (photo)electrochemical sensors for detection of different ionic species in natural water sources and ultra-thin solar cells (UTSC). It focuses on three directions: high efficiency, new materials in solar energy harvesting and fabrication of small UTSC and the power stabilizing device able to supply the needed voltage to the sensors and electronic module; new microsensors for detection of nitrites/nitrates and heavy metals in water; low cost autonomous energy system integration and fabrication. The harvester will include a UTSC, a dedicated storage and a power stabilizing device. SnO2, TiO2, ZnO materials will be optimised for sensors and (TiO2, ZnO, CuxS) or (CZTS, CuxS, TiO2) for the solar cells. Bacterial flagellar filaments will be investigated and engineered as sensitive biolayer for heavy metal detection. The project will provide a technology demonstrator and water monitoring system prototype.
