The ability of organic electrochemical transistors is explored to record human electrophysiological signals of clinical relevance. An organic electrochemical transistor (OECT) that shows a high (>1 mS) transconductance at zero applied gate voltage is used, necessitating only one power supply to bias the drain, while the gate circuit is driven by cutaneous electrical potentials. The OECT is successful in recording cardiac rhythm, eye movement, and brain activity of a human volunteer. These results pave the way for applications of OECTs as an amplifying transducer for human electrophysiology. It is shown that organic electrochemical transistors are able to record cardiac rhythm, eye movement, and brain activity in humans. These devices, therefore, show promise as amplifying transducers for the recoding of electrophysiological signals of clinical relevance.
