The development of electronic and optical systems that harmoniously evolve with dynamic biological and ecological environments is crucial for advancing healthcare and sustainability. In this talk, I will explore the role of dynamic adaptability in materials and manufacturing to advance these systems, and explain how these can address grand societal challenges. First, driven by healthcare concerns, I will introduce a biodegradable electronic device that can serve as ‘medicine’ to eliminate the side effects of drug overdose and enable on-demand therapeutics 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 sustainable, scalable laser manufacturing techniques) to accelerate the deployment of biodegradable electronics into everyday life, with an emphasis on E-waste mitigation. Third, I will present a strategy for the volumetric and simultaneous deposition of diverse functional materials in a 3D, ‘arbitrary’, and nanoprecise manner, and illustrate the utility with examples of 3D optical chips and ultra-compact visible-light optical neural networks to increase computing efficiency and lower energy consumption.
