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.
