| Abstract [eng] |
During the cold season, it is important to maintain a comfortable foot temperature, as cooling the feet can lead to necrosis in the most severe cases. Too high a temperature promotes sweating and discomfort. An adaptive footwear internal heating system is proposed to address this problem. A system has been developed for proof-of-concept, which is autonomously powered by a 3,6 V 4000mAh Li-ion battery, whose current is fed by a microcontroller-controlled swith to a 2-3 W resistive copper polyamide/captone heating element, integrated in the insole. Two sensors are used to measure the internal and external temperatures and the microcontroller uses the readings to adjust the heating power. The system features automatic heating intensity control, temperature change monitoring, a low-energy mode and a minimum of 8 hours of continuous operation. The system shall be mounted on the shoe ball and shall be separate for each shoe. Studies have shown that when the temperature of the insole of the shoe cools down to 24°C, the wearer quickly feels discomfort and when it drops below 20°C, an unacceptable cold sensation occurs. Above 40°C, discomfort due to heat is experienced. The optimum internal temperature of the shoe should be maintained in the range of 26 - 28℃. |
