METODO PARA FORMAR UN CALIBRADOR DE LA DEFORMACION.

摘要

A strain gauge comprised of a premagnetized ferromagnetic film wherein any change in length of the film is converted into a planar Hall voltage by employing the property of magnetostriction and the planar Hall effect. Alternately, a change in the length of the film can also be measured as a change in electric conductivity by employing the properties of magnetostriction and magnetoresistance. The strain gauge is deposited on a substrate by thin-film techniques and has a very high sensitivity.
