The rheological properties of human skin and scar tissue

We have described the rationale and methodology for in vivo strip biaxial testing of human skin1–4. In summary, we have designed a force-displacement transducer which is bonded to the forearm skin using cyanoacrylate glue (Eastman 910). The transducer’s configuration constrains the skin sufficiently in its lateral extent to prevent any appreciable change in its transverse dimension. Thus changing the longitudinal dimension provides information on two dimensions.
