Stress and field contactless sensor based on the scattering of electromagnetic waves by a single ferromagnetic microwire. Applied Physics Letters 2014;105:092405. https://doi.org/10.1063/1.4894732 0003-6951 10.1063/1.4894732 https://hdl.handle.net/20.500.14352/33983 http://dx.doi.org/10.1063/1.4894732 http://scitation.aip.org/ In this paper, we report an experimental study on the microwave modulated scattering intensity for a single Fe_2.25Co_72.75Si_10B_15 amorphous metallic microwire. The modulation is driven by applying a bias magnetic field that tunes the magnetic permeability of the ferromagnetic microwire. Furthermore, by using a magnetostrictive microwire, we also demonstrate that the microwave scattering is sensitive to mechanical stresses. In fact, we present a wireless microwave controlled stress sensor, suitable for biological applications, as a possible use of this effect. In addition, a first order theoretical approximation accounts for the observed influence of the magnetic permeability on the scattering coefficients. That model leads to predictions in good agreement with the experimental results. eng open access Stress and field contactless sensor based on the scattering of electromagnetic waves by a single ferromagnetic microwire journal article
