The design of wearable chemical sensors plays a key role towards the development of Internet of Things technologies and personalised medicine, where real-time and non-invasive monitoring of biological parameters could dramatically impact on the quality of life. At the same time, essential sensor requirements such as conformability, robustness and simple architecture [1] are also shading light on the limited applicability of conventional electrochemical sensors. On one hand, alternative sensing architectures based on organic electrochemical transistors (OECTs) have been showed to interface the biological domain providing intrinsic signal amplification, ease of miniaturisation and sensing capabilities without the need of a freestanding reference electrode
