A system and method for measuring contact pressures between two surfaces, and
especially,
between the body and a device resting on the body, e.g., the skin and a breathable
gas mask. A deformable, resilient probe having a flow passage therein is initially
placed between the two surfaces such that the flow passage is blocked. Fluid pressure
within the probe is then increased until the pressure in the probe overcomes the
contact pressure between the two surfaces, such that fluid begins to flow through
the flow passage in the probe. The pressure at which the fluid begins to flow through
the flow passage in the probe is recorded as the contact pressure between the two
surfaces. Contact pressure maps created using this apparatus and method may be
used to create anthropometric models of the face and other body parts.
