Abstract

Recent advances in mechanics and materials provide routes to integrated circuits that can offer the electrical properties of conventional, rigid wafer-based technologies but with the ability to be stretched, compressed, twisted, bent and deformed into arbitrary shapes. Inorganic electronic materials in micro/nanostructured forms, intimately integrated with elastomeric substrates offer particularly attractive characteristics in such systems, with realistic pathways to sophisticated embodiments. Mechanics plays a key role in this development by identifying the underlying mechanism and providing analytical solutions to guide design and fabrication. I will present our research on stretchable silicon [1] and its applications to stretchable and foldable circuits [2], electronic-eye camera [3,4], semi-transparent and flexible LED [5], epidermal electronics [6], dissolvable electronics [7,8], injectable, cellular-scale optoelectronics [9], and soft, microfluidic assemblies of sensors, circuits and radios [10]. Review of stretchable electronics has been published [11].
