Frequency Characteristics of Ultrathin and Transparent Organic Electrochemical Transistors with 1-µm-Thick Parylene Lamination

Organic electrochemical transistors (OECTs) can be applied to biosensors because of their low operating voltages and mechanical flexibility. In this study, we developed a lamination process for transparent OECTs using 1-µm-thick Parylene films. The OECTs exhibit light transmissions exceeding 80%, operating voltages of 0.6 V, and frequency characteristics of approximately 50 Hz. Furthermore, the la...
