The skin 2D electrobioimpedance response to a remote non-thermal mm-EMF exposure: phenomenological study

A new skin impedance imaging device enabled us to monitor the Skin Electro-bioimpedance Relief (SER) processes such as initial autowaves and induced wave-like dynamics. The SER's response to a remote non-thermal mm-EMF input was investigated in the skin "bioactive" zone (MC7; 20/spl times/40 mm) of healthy subjects and subjects suffering from vegetal-vascular dysfunction. No significant changes were seen in healthy subjects. In unhealthy subjects, in response to switching on of the mm-EMF, a speed of the dominating coherent structure (CS) increased sharply from fractions of mm/min to about 5-7 mm/min; suppression of the neighbouring CS was also observed. In response to switching off of the mm-EMF input, a reverse jump (5-7 mm/min) of the dominating CS back front and reemergence of the neighbouring CS was seen.
