Company Details

NerOcean is a sensor company based in Hong Kong and established by a group of professional scientists and engineers from City University of Hong Kong (CityU) and the Education University of Hong Kong (EdUHK).
NerOcean fosters the sustainable development of the marine ecosystem through our next-generation sensors. We focus on the R&D of new detection methods for various water quality parameters and commercializing the sensors based on the new methods at a lower cost and maintenance against biofouling (the growth of biofilm on the sensors, which affects sensor performance).

Our technology has obtained several international innovation invention awards, including Silver Medal in Innovation Geneva 2022, Top 10 Best innovation Award, Gold Medal, and OCIIP Special Award in iCAN 2022.
Our first product, dissolved oxygen (DO, oxygen content in water) sensors, is based on an entirely new sensing technology – replaceable photo-sensing film - a collaborative effort by CityU and EdUHK. The sensor performance is not affected by biofouling, thus reducing the maintenance cost of long-term operation by up to 10 times, especially in remote areas. Our technology is a breakthrough for long-term continuous water quality monitoring as it makes 3D DO monitoring as affordable as possible!
Based on our revolutionary invention of sensing methods at a reduced cost, we will develop a water quality monitoring network called “Nerve of the Ocean” to provide a cost-effective solution for sustainable environmental monitoring and management, especially for fisheries.
