Abstract
Implantable and resorbable electronic devices show excellent potential for short‐term medical monitoring, especially in the context of post‐surgical care. Bioresorbable sensors are of special interest, as they eliminate the need for surgical retrieval, thereby reducing patient risk and clinical burden. In this work, Polydioxanone (PDO) is explored, a medically licensed, flexible, resorbable material, as a promising substrate for the integration of bioresorbable electronic components. Using a targeted, bottom‐up approach, the feasibility of integrating basic electronic elements and sensors is demonstrated directly on PDO, including resistive temperature sensors, conductivity sensors for electrolytic environments, organic electrochemical transistors, and passive antennas for potential wireless communication. This work highlights the potential of PDO as a platform material for future fully resorbable medical devices and contributes to the growing toolkit for fully resorbable sensor technologies.
