Epidermal device measures blood flow

IEEE Spectrum (Oct. 30) -- A team of researchers with members from institutions in China and Illinois has announced the development of a thin film device that can be affixed to the skin to measure blood flow. The blood flow device works by slightly heating the skin and then temperature sensors record the movement of the heat as arteries and veins near the skin surface carry the heat away. That information is then run through models that account for the fluid dynamics of blood flow, according to John Rogers, one of the inventors.
