This article explores a possibility to determine blood glucose level in a non-invasive way. Environment similar to human body was simulated in software "Comsol Multiphysics 4.3a" and most suitable topology of interdigital electrodes was chosen. These electrodes were used to carry out investigation of blood glucose levels in several test subjects. Non-invasive measurement method decreases possibility of infection and physical injuries.

This article explores a non-invasive method to determine interstitial fluid level and pressure in tissue. Interdigital electrodes were chosen by simulated results in software “Comsol multiphysis 4.3a”. Environment model similar to human body was created. Measurements were carried out at different situations which can occur during preoperative and afterwards surgery. Non-invasive method decreases possibility of infection and will improve recovery process in postoperative period.
