Thermal comfort evaluation based on physiological parameters is a new method for thermal environment quality assessment.In order to improve practicability of this method

a kind of wearable acquisition module of multi-physiological parameters is designed.Data acquisition and communication is based on Zig Bee technology

PVDF sensor

semiconductor temperature sensor and principle of Ω/V transform are adopted to respectively measure pulse

skin temperature and skin resistance.The experimental results show that skin temperature and skin resistance on wrist are measured reliably by module

RRI sequences are also extracted from the pulse signal

and data transmission is normal.This module collects physiological signals conveniently in the natural state of user is advantageous to the research and application of comprehensive evaluation for thermal comfort based on multiple physiological parameters.
