摘要:
The present invention provides a hand-held, noninvasive diagnostic device for measuring the electric fields in mammalian skin and other epithelial structures. The device includes an outer housing that contacts the skin, providing stability and allowing the device to move along with minor movement of the skin. Recessed within the outer housing is a probe that acts as a sensor to measure the electric field in the skin through an aperture in the bottom surface of the outer housing. By applying a series of known voltages while the probe is vibrating, the skins local surface potential can be measured and the lateral electric field can be calculated from the spatial distribution of surface potential measurements. Active feedback is used to maintain a constant distance between the probe and the skin surface.
