The development of circuits and devices that seamlessly adapt to dynamic biological and ecological environments is crucial for advancing human and environmental healthcare. In this talk, I will explore the concepts of dynamic adaptability in these device systems, and explain their potential to address grand societal challenges. First, I will introduce a biodegradable electronic device designed to function as medicine, effectively mitigating drug overdose side effects and alleviating nerve pain on-demand within clinically relevant timeframes. Second, I will discuss the engineering innovations in device functionalities and manufacturing approaches (e.g., the development of the first biodegradable micro-electromechanical systems (MEMS) and advancements in scalable, high-speed laser manufacturing techniques) to accelerate the deployment of biodegradable electronics into everyday life. Third, I will present strategies for the volumetric and simultaneous deposition of diverse functional materials in a 3D, ‘arbitrary’, and nanoprecise manner, exemplified by creating 3D optical chips and ultra-compact visible-light all-optical neural networks for medical imaging.
