Abstract
The elastic properties of skin are measured by applying a torque to a disc placed in contact with a portion of the skin while holding a guard ring against skin around the region to define an annular skin sample to be stressed. Rotation of the disc is measured, and then the rotation is partially reversed and the torque-applying connection to the disc removed. The recovery rotation of the skin in the substantial absence of any applied torque is then measured.
