Fig. 1: BNP detection results based on Au-electrode.
From: Low limit of detection of the AlGaN/GaN-based sensor by the Kelvin connection detection technique
a Change of RCT in the EIS with the surface functionalization process. The inset is the circuit model used to simulate the RCT value. Z′Re is the real part, and Z′Im is the imaginary part of the impedance in the EIS of the Au electrode. b Change in RCT at different concentrations of BNP.
