METHOD AND DEVICE FOR MEASURING STRAIN USING SHAPE MEMORY ALLOY MATERIALS |
摘要 |
An article and method for measuring strain using a strain gauge made of a shape memory alloy, and preferably a pseudoelastic alloy, is disclosed. The strain gauge includes an element that preferably is attached to a substrate and mounted on an object, or is woven or stitched to a fabric to measure the strain experienced under an applied stress. The preferred pseudoelastic alloy is Nitinol, which in pseudoelastic form can elongate by up to approximately 8% to accommodate strain in an object or fabric. When woven into a fabric, a Nitinol-based strain gauge can measure strains of up to approximately 20% in the fabric. The strain gauge can be used in such applications as automotive and aircraft seatbelts, parachute canopies and static lines, and commercial cargo nets. |
