Abstract: Indexes and methods used to measure and evaluate the physiological characters of human body and clothing micro climate were discussed and analyzed. The technology of sensor, LCD was applied to collect, transmit, display and record the signals from human body and clothing micro climate. The system which can be used for smart clothing was developed on the basis of single chip microcomputer AT89C52. The result of this research can be used as the basis of applying sensor and display technology into the smart clothing products.

Key words: smart clothing, physiological index, clothing micro climate, sensor technology
