Biophysical and Physiological Evaluation of Electrically Heated Handwear.

Abstract

Five different electrical heating configurations for use with the Navy's Extreme Cold Weather Mitten (NECWM) were studied to determine if tolerance times in cold weather operations could be extended. Four electrical heating configurations were incorporated in the existing polyurethane liner; one configuration used an electrically heated glove from the United Kingdom (UK) Ministry of Defense instead of the existing liner. All five configurations were tested on a Thermal Hand and physiologically to determine thermal insulation and effectiveness in maintaining finger temperatures. The UK glove liner had the highest effective insulation and was the most effective in maintaining finger temperatures in the comfort zone (27-34 deg C), followed by the Fingers/Palm/Dorsal (FPD) heating configuration. In the FPD configuration test, the fingers were <20 deg C after 120 minutes. The NECWM test showed the finger temperatures to be <15 deg C after only 40 minutes of cold exposure.
