The development of organic electrochemical transistors (OECTs) capable of maintaining their high amplification, fast transient speed, and operational stability in harsh environments will advance the growth of next-generation wearable & biological electronics. In this work, we successfully demonstrated a high performance solid-state OECT (SSOECT), showing a recorded high transconductance of 220 ± 59 S/cm, ultrafast device speed of ~10 kHz with excellent operational stability over 10000 switching cycles and thermally stable under a wide temperature range from -50 to 110 °C.
