A single square voltage pulse method(SSVP)has been used as an effective tool to study a great variety of human biophysical information and mind effects. The basic principles of this skin impedance measurement method can be understood in term of an equivalent electrical circuit model and power function for responsive current waveform. Then an two biophysically important parameters, AP and BP in this method. AP is related to the autonomic nervous system and BP is correlated with the blooflow. Many applications of a single square voltage pulse method is presented, some examples of which are responses to various kind of stimulus, audiovisual effects, color effects, biological rhythms, autonomic nervus functions, Zen and Qi-gong.
