How long has electrodermal technology been used?
The theory of acupuncture and meridians dates back to the Yellow Emperor 2000 years B.C. The electrical nature of acupuncture and its clinical relevance was first discovered by Reinhold Voll, M.D. in Germany in 1953. Voll applied radio technology in recording the effects of electrical stimuli at acupuncture points. He also observed by, serendipity, the effects on a subjects prostate point, before and after, the electrical field of the prostate meridian was exposed to a homeopathic remedy.

The technology was made public at an international meeting of acupuncturists in Limburg, Germany in 1955. In 1937 Alec Reeves discovered the concept of pulse width modulation of analog waves. The an analog to digital integrated circuit that he developed converted voltage to frequency. This discovery led to digital audio recording and was subsequently applie
