A large part of our activity is focused on basic research. Some keywords are electrode systems, modeling, reciprocity, electrodermal response, universality, and memristive processes.

Even though we are not aware of it, our skin is active most of the time, in the sense that it’s electrical properties such as the skin conductance and the skin potential change over time and display waves which can occur every few seconds. The seat of this phenomenon is mainly the sweating.

In this project we utilize the fact that the sensitivity of a two-electrode bioimpedance measurement will be proportional to the square of the current density. Hence, using a needle tip as one of the electrodes in a two- or three-electrode system, will enable us to measure only on the properties of the tissue in the close vicinity of the tip, where the current density is very high.
