Thin film interdigitated electrode arrays applicable for non-invasive monitoring of human skin

The general principle of the human skin electrical properties measurements is a special configuration of the electrode system with electric field lines of vector intensity E cross (transversely) planar structures of skin. An application of the electrode systems for electric parameters measurement in dermatology has to take in consideration the relation between thickness of the skin and the distance of electrode. Electrical properties of the human skin measuring system have been simulated using program PSpice and QuickField. With aspect of theoretical and simulated analysis non symmetric IDA electrode arrays system were designed and fabricated
