Abstract
A new technique has been developed to determine accurately the clothing pressure, which is defined as the pressure applied onto the human body perpendicularly to the skin surface by clothes, particularly by foundation garments. A thin small rubber air cushion, 1 mm thick and 30 mm in diameter, is used as a pressure sensor. Two pieces of platinum wires of 0.1 mm in diameter is attached, at right angles, to each inside of the air cushion, so that the pneumatic pressure inside the air cushion breaks an electrical contact. The air cushion is inserted between clothes and the human skin. Then, the air cushion is inflated with air up to such a state that a pneumatic pressure will just break the electrical contact. The pneumatic pressure inside the air cushion, at just time when the electrical contact is broken, indicates the clothing pressure. Two kinds of girdles were tested to distinguish the difference of the clothing pressure, proving that this technique can be applied to the human body with an acceptable accuracy.
