Significance We successfully performed the intracellular action potential recording using organic electrochemical transistors (OECTs). A simultaneous multipoint recording with a 4 × 4 matrix of 5- × 5-μm2 OECTs demonstrated the feasibility of potential high-resolution recording. The intracellular access was obtained by applying a pulse voltage to the drain electrode, and the amplitude of recorded signal reached 93 µA at maximum. This simple intracellular access method offers a higher signal-to…
