Model for Wireless Magnetoelastic Strain Sensors.

This paper describes a magnetoelastic strain sensor based on the ∆ effect and discusses some materials used in its construction. A polycrystalline Fe-Al-B alloy with good quality magnetoelastic properties was used as the transducer and glued to the test object, either brass plates or rods of SAE 1010 steel. The strain-dependent magnetic field of the transducer changes the operating point of the resonator, a strip of field-annealed Metglas 2826MB3, resulting in a modification of its resonant frequency.

Magneto-elastic biosensors: Influence of different thiols on pathogen capture efficiency.

Magneto-elastic biosensors have mass sensitivity to biological species, offering reliability and reproducibility in the detection of pathogens such as Escherichia coli. In this work, amorphous ribbons of Metglas 2826MB3 were coated with layers of Cr and Au by DC magnetron sputtering and cut to 5mm×1mm. The influence of different thiols on captured pathogens was studied.
