(A) Conventional setup of a potentiometric measurement and corresponding electrical circuit (B). (C) Scheme of the OECT setup proposed by Wrighton's group (Kittlesen et al., 1984; Paul et al., 1985) and corresponding electrical circuit (D). (E) Scheme of OECTs that are commonly used in literature and corresponding electrical scheme (F). (G) Scheme of here-proposed OECT for potentiometric measurements and corresponding electrical scheme (H).
