Fig. 5From: Optimization design of interdigitated microelectrodes with an insulation layer on the connection tracks to enhance efficiency of assessment of the cell viabilityIllustrates the GUI that enables the user to interact with the microfluidic impedance system. As seen in A the GUI allows selecting and defining the connection port connecting to the Arduino microcontroller. B fig. shows the sweep settings panel, which sets the amplitude of the excitation signal and frequency range and specifies the sweeping frequency’s start and endpoints. Finally, C of the fig. displays the output signal features, including the amplitude and phaseBack to article page
