Development of an automatic 16-channel multiplexer platform for capacitive field-effect sensors
A multiplexer platform for the automatic electrochemical characterization of up to 16 individual capacitive electrolyte-insulator-semiconductor field-effect sensors is presented. CAD (computer aided design) models of the top and bottom part of the multi-cell are compared to their 3D-printed counterparts. The functionality of the 3D-printed multi-cell and written Python script is demonstrated by the quasi-simultaneous pH characterization of 8 different sensors by means of capacitance-voltage and constant-capacitance measurements.
