This technology offers several advantages over traditional sensors, particularly in terms of maintenance and performance. Unlike conventional sensors that are susceptible to biofouling—which necessitates frequent maintenance and increases operational costs—this new sensor minimizes such issues, allowing for reduced maintenance frequency and lower long-term costs. The sensor has been validated in real-world conditions through collaborations with the State Key Laboratory of Marine Pollution and local conservation departments.

The development of this DO sensing technology is a collaborative effort between the City University of Hong Kong and the Education University of Hong Kong, with patents filed in multiple regions including the USA, Europe, and China. Recognized for its innovation, this technology has received several awards, including a silver medal at Inventions Geneva 2022.
