Since the development of the first non-sweating, single segment copper thermal manikin by the US Army in 1940s, there have been numerous developments worldwide in thermal manikin technologies. Nevertheless, the simulation of perspiration has continued to be one of the major challenges. Inspired by the thermoregulation system of the human body, a novel sweating fabric manikin nicknamed “Walter” has been developed in Hong Kong Polytechnic University. The new sweating manikin achieved perspiration over the entire body and a very high measurement accuracy (viz. a CV of less 5%), yet with a cost of only a small fraction of other sweating manikins developed so far.



The improved Walter Sweating Fabric Mannequin has been used to study the influence of walking motion on clothing insulation and evaporation resistance, including improved "walking motion" simulation, design and construction of automatic water supply, and real-time measurement by adjusting the pump inside the human body Evaporate water loss and regulate "skin" temperature. Tests on commercial clothing suits show that the measurement of clothing’s thermal insulation and moisture resistance has good repeatability, and the coefficient of variation is generally less than 5%. In addition to heat insulation and moisture resistance, the percentage of moisture accumulation in clothes is a very useful parameter to measure the comfort of clothes.
