Figure 4. Response of a textile OECT in configuration G1.

Figure 4

(A) Id vs. time curve (Vg = −0.9 V; Vd = −0.3 V) obtained after the addition of different adrenaline amounts. The additions are labeled with arrows indicating the increase of concentration. (B) 1 − I/Imax vs. LogCAA plot. (C) Working principle of textile OECTs.: the PEDOT:PSS channel exhibits a potential which is high enough to electro-oxidize adrenaline. The reaction is also reported in simplified form in the panel according to Coppedè et al.20. The oxidation leads to hole extraction from the transistor channel material and, thus, Id decreases.
