Design and Development of Hypothermia Prevention Jacket for Military Purpose
This article discusses the design of a jacket that will help the military personnel stationed at the extreme cold climatic conditions to prevent going into hypothermia, a medical condition where in the core body temperature drops below 35 °C (95 °F), which causes shivering, mental confusion and ultimately leads to death. Our aim is to develop an external heating system in the form of heating pads that will aid the body to avoid going into hypothermia state. The set of three heating pads are controlled through a programmable microcontroller and temperature sensors. The pads are allowed to get heated only within the set range i.e. 37–45 °C. All these components are finally embedded in a polar fleece jacket which is an ideal substitute for wool and is much lighter than its predecessor. An inner layer of styrofoam and copper sheet lining helps in further distribution of heat evenly to the rest of the body surface. Thus, a virtual environment (around 37 °C) is created around the human body and does not allow it to lose heat further. This reduces the hypothermic effect on the body by preventing the loss of heat from the body to the cold surroundings, and hence makes the individual feel much better in such harsh climatic conditions and prevents any adverse effects from happening.
