Organic electrochemical transistors (OECTs) have attracted considerable interest in the context of wearable and implantable biosensors due to their remarkable signal amplification combined with seamless integration into biological systems. These properties underlie OECTs’ potential utility across a range bioelectronic applications. One main challenges practical applications is mechanical limitation PEDOT:PSS, most typical conductive polymer used as channel layer, when OECTs are applied stretchable bioelectronics. In this work, we address critical issue by employing natural rubber latex (NRL) an additive PEDOT:PSS improve flexibility stretchability OECT channels. Although inclusion NRL leads decrease transconductance, mainly reduced carrier mobility from 0.3 0.1 cm2/V·s, maintain satisfactory exceeding 5 mS. Furthermore, it demonstrated that exhibit excellent stability while maintaining performance even after 100 repetitive bending cycles. This therefore, suggests NRL/PEDOT:PSS composite film can be deployed for wearable/implantable applications, where high needed. finding opens up new avenues use more robust versatile biosensors.
