BLOOD GLUCOSE MEASUREMENT BY SWEAT USING ARDUINO

This work investigates the effect of blood glucose measurement by conductivity measurement technique. Sweat contains dissolved ions, which contribute conduction between the two copper electrodes. As the concentration of ions in the sweat increases, conduction increases. The measured parameters such as voltage from the copper sensor is given to Arduino controller and then to the LCD display. Normal person have voltage range of 320 conductivity / sec and its corresponding glucose level is 80mg/dl. For diabetic person the voltage range is 377conductivity/sec and its corresponding glucose level is 141mg/dl. The responses are studied as salt content in the sweat is high, which results in high glucose level. If salt content in the sweat is low, it result in low glucose level. The correlation between salt content in sweat with its corresponding voltage and glucose level is done by interpolation equation. Non-invasive blood glucose estimation framework is utilized to quantify the blood glucose without taking the blood test. Hence, this method of blood glucose measurement is said to be painless, cost effective and easy monitoring for diabetes person
