Wearable Sensors Based on Stretchable Organic Transistors

ABSTRACT Organic electrochemical transistors (OECTs) hold potential for in‐sensor computing and wearable healthcare systems. Nevertheless, their inherent limitations in stretchability and conformability hinder their scalability and practical deployment. In a recent study, Liu et al. introduce a wearable in‐sensor computing platform that leverages stretchable OECTs, exhibiting over 50% elongation capability while preserving stable operational performance. This innovation enables the development of wearable systems that can accurately acquire biosignals.
