Abstract

Changes in skin potentials are known to occur upon stretching and compressing the skin. In this work the relationship between compressional force and changes was studied for forces up to 13·7 N. For a given force, a flatter compressing surface gave lower potential changes than a more curved surface. When temperature increased both changes in potential and current decreased.
