Recent advances in electronics enable powerful biomedical devices that have greatly reduced therapeutic risks by monitoring vital physiological signals and providing means of treatment.  Better understanding of many unknown diseases could be achieved if implantable devices could be exploited for monitoring.  However, an expensive second surgical operation would be needed to remove the devices after an initial implantation.  In addition, conventional electronics require components to be formed on planar surfaces of brittle wafer substrates, which is not compatible with the complex topology of body tissues.  Therefore, stretchability and resorbability are the two missing links to realize implantable monitors and in-vivo therapeutics.  To address these challenges, I propose to design a stretchable medical device that can (a) conform to a complex topology of human organs and (b) function during its lifetime and then completely resorb after use.  Implanted devices will provide a much better understanding of how each organ functions and offer more timely treatments for serious diseases such as heart failure.
