Abstract
A magnetoresistive acoustic wave sensor with high sensitivity and an array device thereof is disclosed, in which a magnetoresistive acoustic wave sensor comprises a protective tube shell, a magnetic vibration assembly, and a magnetoresistive chip located inside the protective tube shell. The protective tube shell comprises at least one opening which is covered by the magnetic vibration assembly. The plane where the magnetoresistive sensor chip is located is perpendicular to the plane where the magnetic vibration assembly is located, and the sensing direction of the magnetoresistive sensor chip is located in the plane where magnetoresistive sensor chip is located, and is perpendicular to or parallel to the plane where the magnetic vibration assembly is located. Alternatively, the plane where the magnetoresistive sensor chip is located is parallel to the plane where the magnetic vibration assembly is located, and the sensing direction of the magnetoresistive sensor chip is located in the plane where the magnetoresistive sensor chip is located, and is parallel to the plane where the magnetic vibration assembly is located. The magnetoresistive acoustic wave sensor with high sensitivity…
