Potential and impedance variations following skin deformation

Potential and impedance variations were studied with varying mechanical stress upon the skin. The size of the potential variations in the skin and the mechanical stress possess a nonlinear relationship which varies between individuals. The impedance variations did not bring about the potential variations. The time sequences for impedance and potential variations do not have the same form when the skin is stressed as when it is relaxed. The rapid initial potential variation upon stressing had a calculated rise time of 30 ms. The rise time during relaxation was 40s. The difference in rise time gives the relationship between potential and deformation a nonlinear character.
