Abstract
Organic electrochemical transistors (OECTs), functioning as transduction amplifiers, demonstrate considerable potential for integration into biosensors and wearable technologies. However, conventional OECTs demonstrate limited stability in conformal sensing on biointerfaces, primarily due to their poor ductility and liquid-electrolyte-gated operation mechanisms. A double-network-based stretchable gel electrolyte is presented, simultaneously integrating exceptional mechanical compliance and high ionic conductivity. OECT arrays, gated through photopatterned gel electrolytes, demonstrate high uniformity in electrical performance. Besides, the solid-state devices show remarkable electrical stability when subjected to 50% strain, thus facilitating continuous electrocardiogram monitoring under mechanical deformation. This validates its application potential in ambulatory healthcare systems requiring long-term biosensing.
期刊介绍:
Science China Materials (SCM) is a globally peer-reviewed journal that covers all facets of materials science. It is supervised by the Chinese Academy of Sciences and co-sponsored by the Chinese Academy of Sciences and the National Natural Science Foundation of China. The journal is jointly published monthly in both printed and electronic forms by Science China Press and Springer. The aim of SCM is to encourage communication of high-quality, innovative research results at the cutting-edge interface of materials science with chemistry, physics, biology, and engineering. It focuses on breakthroughs from around the world and aims to become a world-leading academic journal for materials science.
