摘要： This invention relates to a load sensor comprising a member composed of electrically conductive magnetostrictive material. The member is a uniform and continuous distribution of wire or strip material abutting itself between opposite ends. The magnetostrictive material is annealed and abutting portions of the member are spaced apart from one another using insulation incorporating microspheres. Terminals at different portions of the member allow the member to be electrically connected in a circuit for measuring an impedance of the member. Stress applied along an axis of the member causes a change in the member's permeability that is measurable as a change in impedance of the sensor. The configuration of the sensor can be described as coil shaped or accordion shaped. The wire or strip material comprising the sensor comprise a variety of shapes. Insulation comprises a high strength adhesive filled with high strength ceramic microspheres. A method is also taught in the present application to fabricate the load sensor of the present invention.
