Abstract：Objective To solve the problem that microcirculatory dysfunction threatened human health but was difficult to diagnose,
an effective non-invasive assessment system of microvascular was designed. Methods The system was constituted by STM32 control
board, heating plates, TMP117 high precision temperature sensor and PC communication module. The heating plate was used to heat
the skin of finger. The temperature sensor collected the temperature signals before and after thermal stimulation, and transmitted them
to the time-frequency analysis software on the PC. Then, the signals of endothelial, neural, myogenic regulation were extracted to
further evaluate the microvascular function of human body. Results The subjects were tested using the system, the assessment scores
of healthy individuals were above 60, and those at risk of microvascular function were below 60. The better the health condition, the
higher the score. Conclusion The system is easy to use and low cost, which is of great significance for early screening and evaluation
of diseases.
