The overall project, funded by IRSST, focuses on the problem of cold intolerance in the workplace. Cold intolerance manifests itself primarily in the hands through pain, numbness, stiffness and color changes, and can also lead to loss of dexterity, discomfort and dysesthesia. This can lead to cessation of activities or career changes to sectors with more tolerable and warmer environments for the affected individuals. One effective means of prevention is the use of heated gloves. The current range on the market, aimed primarily at the winter leisure and outdoor sports market, is not adapted to working conditions and the handling of vibrating tools. This is reflected, for example, in the deterioration of heating elements and connections between electronic components, which break down in fatigue under the effect of vibrations. In the absence of satisfactory solutions adapted to working conditions, the aim of this project is to develop and explore the potential of heated gloves, based on recent advances in printable electronics, to provide a technological solution to the problem of cold intolerance in the workplace. One of the project's major stages therefore involves designing and manufacturing the heating element, as well as studying its functional properties. The aim of this stage is to determine the shape and positioning of the heating elements, as well as their electrical power, based on the target weather conditions. The design process therefore involves selecting the most suitable pattern to ensure uniform heating of the hands and fingers. Several patterns may be designed and tested; examples include S-curves and fractals, such as Peano curves. At the same time, the power and operating temperature of the printed circuit must be determined to ensure that the temperature does not exceed 43°C upon skin contact, thereby avoiding any risk of burns. Finally, with regard to the design, it will be possible to refer to existing simulation models or develop one if necessary.
