Abstract
When mounted on to the skin, such modern sensors, devices and circuits have the powerful potential to provide clinical-quality health monitoring capabilities and precise sensing accuracy for continuous use, beyond the traditional hospital or laboratory facilities. The present high development technologies are, however, broadly available in hard, planar formats. As a result, existing options in system design are unable to integration with soft, textured, curvilinear, and dynamic surfaces of skin. In my thesis, I worked on describing experimental approaches for using ideas in soft microfluidics, structured adhesive surfaces to achieve highly stretchable systems that incorporate high-modulus, rigid, state-of-the-art functional elements. The result is a thin, comfortable device technology that can softly laminate onto the surface of the skin to enable advanced, multifunctional operation for physiological monitoring and UV sensing in a wireless mode. Skin cancer has become an increasing issue in human health. Skin cancer has become the most common form of cancer in the United States, with more than 3.5 million cases diagnosed each year. Over the past three decades, more people have experienced skin cancer than all other types of cancer combined. As a result, people are becoming more concerned about gauging their exposure to the ultraviolet (UV) radiation that is, for the most part, responsible for the formation of skin cancer tumors. UV radiation is a natural part of the environment and even has a beneficial effect in smaller does. If we tried to eliminate all UV exposure, we would see an increase in skeletal diseases caused by the deficiency of vitamin D that is synthesized by the body with the help of UV. How much of a health benefit we see from UV depends on personal circumstances, since there are strong interactions between UV exposure and skin pigmentations. The key is to maintain UV exposure at an optimum healthy level but not so high that it becomes dangerous.
