Improved electrodes

Deliverable D3.7 comprises the design and optimization of the sensor electrodes towards the final selected target compounds. This deliverable is in direct continuation of D2.5, D3.2 and D3.3, where the outcome of several important deliverables converge. The results of the compound stability tests will determine the final selection of compounds which should be detected (D2.5). A better knowledge of the sewage constitution will identify potential challenges for the sensor operation and allow to modify and improve the sensor surface. The prototype of the ASIC and the electrodes will be evaluated internally (D3.2) and the full sensing subsystem will be tested externally (D3.3). The results of these tests are a first and important evaluation of the integrated sensing system prototype and will provide insight into the working of the sensing system as a whole. This information will be used to improve or change the sensor electrodes and thus adapt the multi-array towards the final sensing system. The robustness of the electro-chemical sensors towards ATS specific compounds in waste water will be evaluated and, if needed, improved.
