Hemispherical golden electrodes with a radius of 250 µm were developed as part of a project aimed at detecting early signs of urinary tract infections. The system utilizes a combination of spectral and conductimetric analysis of urine, achieved through an integrated 'optrode.' This innovative approach enhances the detection capabilities by providing comprehensive analysis through both optical and electrical measurements.
All the connections with the electric wires are insulated from the environment with an epoxy resin. These electrodes are tiny and their fabrication can be automated.
