Live demonstration: A portable multi-channel potentiostat for real-time amperometric measurement of multi-electrode sensor arrays

摘要

We demonstrate a portable PCB prototype of a potentiostat capable of driving an 80-electrode sensor array with 5 readout channels. Controlled by a MATLAB graphical user interface, the system demonstrates real-time data acquisition and achieves similar performance to a commercial potentiostat based on electrochemical validation.
