Title:
STRESS SENSOR
Document Type and Number:
Japanese Patent JP2015215230
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a stress sensor capable of detecting stress with high accuracy.SOLUTION: A stress sensor 1 includes: a shaft-shaped member 10 that receives stress in a predetermined detection direction; a cover member 2 that covers at least a part of the shaft-shaped member 10; and a magnet 3 and a magnetic field detection element 4 that are arranged between the shaft-shaped member 10 and the cover member 2. The N pole of the magnet 3 is arranged on the side of the shaft-shaped member 10, and the S pole thereof on the side of the cover member 2. At least one member of the shaft-shaped member 10 and the cover member 2 comprise a magnetic body whose magnetic permeability changes according to stress. Magnetic flux detected by the magnetic field detection element 4 changes with change of the magnetic permeability.
