Water quality monitoring used to be laborious, time-consuming, costly and in some rural areas, inaccessible. Stephanie developed a hand-held sensor that can detect various heavy metals such as cadmium and lead in five minutes, at a fraction of the cost of conventional measurement. It is also more affordable for public and private use, allowing for water quality monitoring to be conducted thoroughly and frequently. Using the developed sensing platform, Stephanie is currently working on extending the applicability of the sensor for other organic and biomolecule water contaminants as well as incorporating IoT for large-scale distributed sensing.
