Abstract
Measuring foot temperature is considered as an important for physiological studies as well as clinical investigations. It also helps in diagnosing and preventing many diseases like foot ulcer, diabetic neuropathy, etc. Foot ulcers are very common in diabetic population. In recent years, numerous observations have been reported and various methods of measurement have been employed. But all the existing systems were bulky and not more accurate. A system is proposed to measure the foot temperature very accurately to overcome the existing demerits. The proposed system introduces a novel temperature sensor, STS21 with 0.01°C accuracy for human foot temperature measurement. In addition, the temperature measuring system is made compact using Atmega328p microcontroller. The developed system is made to fit in to the shoe and the foot temperature is obtained from the subjects and displayed through PC. Foot temperature readings are taken from various subjects are analyzed to study the efficiency of measurement system.
