Body temperature distribution and blood circulation perfusion factor

Body skin temperature and blood circulation analysis are active research topics in the biomedical field. This project proposes a different approach to estimate blood circulation factor using the body skin temperature readings through thermistors. The temperature is measured on the body skin using the thermistor. The prototype consists of four NTC thermistors and Arduino microcontroller board with cortex-M3 chip in it. The temperature readings taken by the thermistors are passed on to the microcontroller for further processing. A program code is written in C language to convert the temperature readings to estimate the blood circulation perfusion factor. The algorithm used in the program code is based on the bio-heat equation representing relationship between body skin temperature and blood circulation perfusion factor. The temperature observed from the thermistors has 97.8% efficiency. Thus, using the temperature data blood perfusion factor was successfully calculated.
