The probe, called SEMSED, contains a package of electrodes, a computer-controlled channel selector, connected to a commercial potentiostat. The project proposes the advance from TRL4 to a pilot probe, level TRL6, submersible, technologically and experimentally validated. The novelty of the project is the use of CMOS electronic multiplexers / switches to digitally select the combination of electrodes needed to perform electrochemical measurements in sediments. Another novelty is the realization of solid reference electrodes and software dedicated to commands and communication. The ability of the probe to monitor sediment evolution without physical disturbance (as opposed to equipment on the market) is very important in analyzing how sediments change (increase and decrease, and how their chemistry changes between aerobic and anaerobic). This probe can be placed in freshwater or seawater and will monitor changes in chemical composition in sediments from ports, canals, lakes, estuaries, aquaculture biofilters, sapropelic sludge as well as sediments from settling tanks and sewage treatment plants. SEMSED probes will be located and validated in the field and used to monitor sedimentation rate, the redox status of sediments and identify key chemicals such as oxygen and hydrogen sulfide. The SEMSED probe will be able to operate autonomously (linked or not to an underwater electrical grid) for a long time without maintenance, and without moving mechanical parts, while monitored online. This novel eco-technology will expand the range of monitoring capabilities for users such as: national and European environmental agencies, fish farmers and managers of water treatment plants, canals, ports and waterways.
