Flexible Sensor Technologies for In- Situ Ocean Monitoring

Abstract

We will develop soft marine sensors, which are waterproof and sufficientlysensitive. The parameters to be monitored are temperature, salinity, O2, pH, and nutrient levels of ammonium (NH4 +), nitrate (NO3 -), and phosphate (PO43-). We will build upon the advanced realtime Sea-Bird platform, which is capable of highly sensitive temperature and salinity measurements. The electrochemical sensors to detect O2, pH, and nutrient levels are currently limited to bulky electrodes, which we will minimize by additive printing flexible, low profile sensors onto compliant substrates that will be compact and robust to harsh marine environments. Biofouling and corrosion will be addressed through investigating different electrode materials, coatings, and polymer technologies. Sensor performance will be characterized in representative aqueous environments to assess durability and sensitivity. For all the sensors, we will design experimental protocols and fixtures to enable us to test promising fabrication methods, geometries, layouts for flexibility, variability, and signal quality. The most successful designs will be used for the sensors to be integrated in field tests
