| Popis: | This work presents the design and method of measuring the impedance in a fluidic unit containing a metal solution using a concave capacitive sensor. The prototype of the design is tested with metal solutions over a range of frequency onto a specific concentration. The system is also tested to get the optimal operating frequency of the sensor at different set of frequencies. A graphical model of each sample’s capacitance versus frequency is determined to fit to a mathematical function that describes the frequency dependence of the fluidic unit. The performance of the whole system is demonstrated in an exemplary measurement. |
