Abstract: 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. The developed SSOECTs were successfully used to detect low-amplitude physiological signals, showing a high signal-to-noise-ratio (SNR) of 32.5±2.1 dB. For the first time, the amplifying power of these SSOECTs was also retained and reliably shown to collect high-quality electrophysiological signals even under harsh temperatures (-50°C and 110°C). The demonstration of high-performing SSOECTs and its application in harsh environment are core steps toward their implementation in next-generation wearable electronics & bioelectronics.
