Graphene has come into the spotlight as a new material for display, industry, and so on. The high electrical and thermal conductivity of graphene along with its remarkable chemical and mechanical properties attract researchers of various academic fields. Recently, it has been found that graphene is superior to any other previous material as a heating element because of its flexibility, transparency, fast-heating, and homogeneous temperature distribution. The graphene heater could be suitable for heating elements in winter sports wear because of its flexibility and well-distributed surface temperature. This study was aimed to explore ways to make the graphene heater for winter sports wear and investigate the physiological effect of the graphene heater when applied to winter sports wear. To make large-scale graphene films for a heater, chemical vapor deposition (CVD) method was used. One volunteer subject participated in a pilot test. The subject was exposed to a cold environment maintained at an air temperature of -6℃ and relative humidity of 20%. Subjective perceptions (thermal comfort, thermal sensation, shivering sensation, and humidity sensation) were assessed. Temperature of skin heated by the graphene heater was kept around 50℃. The results showed that rectal temperature was more stable and shivering sensation was lower in the graphene heater applied conditions when compared to Control. However, no significant difference was found among the surface temperature of the skin(AH, BH, and CH). These results indicate that the graphene heater was beneficial for maintaining body temperature during cold conditions and have implications for the development of cold protective clothing in extreme environments.
