Our technology is based on bioimpedance. Bioimpedance provides passive, non-invasive, continuous, digital, self supported measurement of the electrical impedance of different body tissues. This technology is commonly used to measure body composition such as fat, muscle, liquids and blood.
Bioimpedance can be described as the response of a living organism to an externally applied low electric current. The basic structure is demonstrated below:
Bioimpedance technology has been used to examine the correlation found between cardiovascular parameters, the blood’s electrical and dielectric parameters, and blood glucose levels.
An example of a test is presented in the following figure:

The green dots are glucose values measured using a standard home monitoring glucose device. The green bars represent an acceptable error range according to clinical requirements. The blue line is the measurement made using bioimpedance technology.
Our focus is the measurement of blood impedance for the purpose of extracting physiological data such as blood flow, cardiac activity, and electrical and dielectric changes in the blood, relating to the concentration of different substances in the blood.
We are currently working on our main product:
Non-invasive continuous glucose meter
The monitoring of blood glucose levels plays an important role in the daily life and day-to-day treatment of diabetic patients. Current devices on the market are invasive and non continuous, and require patient intervention. This leads to partial information about changes in glucose levels during the day and the physiological processes involved. The patient is not able to use this information in order to take preventive steps.
Our research is based on recording physiological processes during glucose intake and glucose absorption by the human body, and also on the effect of blood composition on measured bio-electrical impedance.
We aim to develop a continuous, passive, non-invasive, digital, self supported, watch-like, personal measurement device for non-stop use by diabetic patients.t
Our technology is based on scientific research undertaken by Dr. Alex Shurubura, a leading researcher in diving medicine. The technology is based on the ratio between the gas volume and the impedance of the blood at specific frequencies. Based on that BIG intends to further develop a real-time, non-invasive, passive, continuous engineering prototype, to monitor the danger of decompression sickness, along with the diver’s vital signs such as cardiac pulse, heart rate, and breathing.
