The conventional acupoint stimulus pattern have used DC for discrimination of acupoint and meridian line which are basic object of diagnosis and medical treatment in oriental medicine. But it is not sufficient to reliance in discrimination and safety of body effect. When the measurement is repeated, discrimination ratio and reproductivity became lower because DC current is decreased proportionately time. It influences to cells and physiological state and causes polarization of cells. So when electrode pressure is increased, DC has long discriminate time and pain results. Also, pulse stimulus type uses high voltage(12V～60V) and frequency of 40hz～200hz, so it makes polarization of cells and ionization of hydrogen. A changeable pulse source causes electrical pain by high and narrow voltage. Its phenomenon is similar to that of DC.
To overcome these weaknesses, we propose the SPAC(Single Power Alternating Current) that minimizes the variables of the measurement pressure, body effect and the skin resistance, and extract optimal parameter of stimulus pattern. The SPAC has square-like waveform with 4Khz of 1.28V, duty ratio 40%. It can minimize polarization and ionization of cells because it uses low voltage and alternative current. So the SPAC can hardly influence to cells and physiological state.
We designed discrimination system using SPAC stimulus pattern and measured low impedance points(LIP) along meridians with three stimulus patterns and compared their electrical characteristics. In the results, the SPAC has more advantages than DC and pulse type, in aspects of pain by high voltage and electrode pressure, safety and physiological influence on body.
