1. A perineal protection device adapted for preventing perineal tear during birth, the device comprising:
a) a reinforcement shield and a support pad that are adapted for releasably connectable to a female perineum of a subject, the reinforcement shield having a surface geometry substantially corresponding to an underlying perineal muscle structure and being configured to reduce deformation of the perineum during childbirth; and
b) wherein the reinforcement shield and the support pad are configured to have reinforcement fibers of varying directional strength in at least two different directions; and
c) at least one sensor including a shear force sensor configured for detecting at least one of: magnitude, direction or location of the shear force;
d) an electroactive material that is in communication with a controller; and wherein the electroactive material is configured to emit a signal responsively to sensing of shear force or a perineum deformation; and wherein the electroactive material is configured to render a change in at least one mechanical characteristic selected form: stiffness, elasticity, flexibility, shape, thickness, or geometric contour and wherein the electroactive material is featured in at least one of the support pad or the reinforcement shield.
