Abstract

(Figure Presented) The response of PEDOT:PSS planar electrochemical transistors to H₂O₂ can be tuned by varying the ratio between the areas of the channel and the gate electrode. Devices with small gates show lower background signal and higher sensitivity. The detection range, on the other hand, is found to be rather independent of the gate/channel area ratio.
