摘要：

Magnetically soft [Ti/FeNi](5)/Ti/Cu/Ti/[FeNi/Ti](4) multilayered structures were obtained by magnetron sputtering. Based on them sensitive elements have been investigated with focus on the design of the giant magnetoimpedance ( MI) pressure sensors. Magnetic properties and MI of fabricated sensitive elements were comparatively analyzed for both multilayers deposited both onto rigid and flexible polymer substrates. Structures on a rigid substrate had the highest MI ratio of 140 %. They showed the sensitivity of 0.70 %/Ba suitable for possible applications in pressure sensing. Structures deposited onto flexible Cyclo Olefin Copolymer substrates had slightly lower sensitivity of 0.55 %/Ba. That structures showing linear dependence of MI ratio in the pressure range of 0 to 360 Ba are promising for microfluidic and biosensor applications.
