A flexible body heater is designed and tested for treating hypothermia. The heater is portable and can be carried to treat hypothermia victims in remote places. It contains a 24-gauge Chromel A (Nickel-80) wire placed between two layers of flexible Silicone Rubber. The ends of the Nichrome wire are connected to a 12V Sealed Lead Acid Battery by means of copper connecting wires with a two-way switch to regulate the circuit. The sample is tested in ambient atmospheric temperature (25°C). When the switch is turned on, current passes through the heating element, which in turn heats up the periphery of the rubber surface to the desired temperature. The flexible heater is applied to the epidermis of the human skin in order to provide sufficient heat. The desired heat is reached in a very short period of time and comfortable heating is obtained. The body part to be heated is identified and the heater is fastened over the skin covering that part. It is capable of operating continuously for a long period of 3 hours. The flexible nature of the heater enables the user to apply it on any body part. When the switch is turned off, the heating element rapidly cools down and returns to ambient temperature.
