Abstract [en]

Bioimpedance is a common feature of every tissue and its analysis allows the understanding of the physiological state of the tissue under test as well as its changes. The increase of glucose concentration can be detected by monitoring the tissue bioimpedance. In high risk situations and subjects like athletes, several checks with high accuracy are required each day. The scientific community has focused its efforts to find an integrated solution for in-vivo implantable bioimpedance measurement devices. The implantable devices have better accuracy since they are placed closer to the tissues under test. The objective of this thesis is to characterize the different shapes and configurations of probes suitable for bioimpedance in-vivo measurement applications. The electrode modeling and simulation, and analysis of its interaction with the tissue are performed by using the electronic design automation software ADS, from Agilent. Two shapes and six configurations are considered and analysed. The chosen geometry is capable of developing the least amount of tissue reaction around the electrode, so as to ensure the best performance for a four-electrode measurement.
