Abstract
When an electric current flows in an electrolytic solution, electrolysis occurs at both poles. In the living body as well, when electrical current passes through a needle inserted into the epidermis, electrolysis at this point results in corrosion.
When low-frequency electrical apparatus is used with the differing factors of waveform, time of electrical flow, distance between positive and negative poles and amount of current, what degree of electrolysis will be produced? With an experimental case utilizing positive-negative spike waveform, and a control case utilizing positive squarewave, differences in the waves were observed and the resulting electrical corrosion was noted.
(1) Among the factors of electrical corrosion (frequency, time of electrical flow, distance between poles), the amount of electricity most influences the degree of electrical corrosion.
(2) If a positive square wave current passes through the needle, breakage of the needle may occur on the needle.
(3) The positive-negative spike waveform, when compared to the positive square waveform, results in almost no electrical corrosion.
