Electropulse Responsivity to Changes in Skin Moisture

Abstract

12 Ss were exposed to electropulse stimulation under 3 moisture treatments: dry, water immersion, and a fluid approximation of sweat. Touch threshold data were obtained under these conditions during the first half of the experiment and electropulse recognition responses during the second half. A significant threshold rise occurred with increased amounts of moisture on the skin. Similarly, recognition accuracy decreased but remained within a 90 to 100% range. Human engineering implications pertinent to a tactual communication system were discussed.
