Advances in materials, mechanics, and manufacturing now allow construction of high-quality electronics and optoelectronics in forms that can readily integrate with the soft, curvilinear, and time-dynamic surfaces of the human body. The resulting capabilities create new opportunities for studying disease states, improving surgical procedures, monitoring health/wellness, establishing human-machine interfaces, and performing other functions. This paper studies the wireless power transfer capability of a soft, flexible and stretchable metamaterials for future use in forms of integrated with the brain, the heart, and the skin.
