To further evaluate the role of the semi-solid-state AWIEG as a self-powered source for electronics, it was used to supply the source-drain voltage for an organic electrochemical transistor (OECT) that comprises PEDOT:PSS in the channel for logic operation (Figure and Figure ). The transfer curve in Figure demonstrates the successful modulation of I ds of the OECT powered by the AWIEG. The changes of I ds (Figure ) when the OECT is connected/disconnected with AWIEG proves its capability to serve as a power source for modulating OECT.
