Electrical Potential of Acupuncture Points: Use of a Noncontact Scanning Kelvin Probe

Figure 2

Topographic maps of electrical potential at LI-4 and control sites. Representative topographic maps from two subjects are shown here. Images on the left correspond to LI-4 while the images on the right correspond to LI-4 Control. The top images are derived from Subject number 1 and the bottom images are from Subject number 5. For each scan, a color bar is included to display electrical potential magnitudes.
