Bioelectric Field Imaging Near Human Skin Wounds

The investigators have developed a new non-invasive medical device called the Bioelectric Field Imager. They plan to use this device to measure the electric field near small lancet wounds in 60 volunteers. Their hypothesis is that the electric field is an early stimulus for wound healing and the magnitude of this field will vary with wound healing capability. The investigators will compare the electric fields near arm and leg wounds in males and females in the age groups of 18-30 and 65-80. In addition they will measure these wound fields in diabetics and near chronic ulcers.
