摘要：
Glass-coated ferromagnetic microwires, with low Curie temperature, used for temperature sensor were designed and complex characterized. Two alloys with low Curie temperature consisting of Fe-Ni-Cr-B-Si and Fe-Ni-Cr-Co-B-Si were developed. The microwires are covered by a thin layer of glass, thus increasing their corrosive protection, making the temperature sensors suited to work in corrosive environments. The active elements have a temperature range between 20°C and 200°C, with a sensitivity that depend on the number of microwires used in the design of the temperature sensor. © 2019, Politechnica University of Bucharest.
