Abstract：Blood microcirculation system is an important part of the cardiovascular system, and its
properties reflect human health, namely, physiological features of cardiovascular system among which
one is endothelial function. Nowadays together with known optic techniques of blood flow monitoring
skin temperature measurements are developed. In this paper, we review recent development of skin
temperature monitoring methods for blood flow analysis and present research progress in numerical
simulations of bioheat transfer reached by the authors. First the basic principle of thermal analysis
method for assessing blood flow is introduced. Furthermore, the advancement for evaluation of
endothelial function basing on skin temperature and temperature oscillation is reviewed. Finally, three
kinds of innovative instruments are presented, including an ultrathin, soft, skin-conforming sensor for
continuous blood flow mapping, blood flow-skin temperature converting software, and an instrument for
diagnostics of endothelial dysfunction.
