我们在自支撑弹性聚二甲基硅氧烷(PDMS)薄膜上制备了具有巨磁电阻效应的[Co/Cu]多层膜，在刚性硅上和在自由支撑的PDMS上制备的[Co/Cu]多层膜的GMR性能相似，并且在4.5%的拉伸变形范围内不会发生变化。由于PDMS膜的弹性，施加在传感器上的机械变形是完全可逆的。这种非凡的拉伸性能依赖于PDMS膜顶部的GMR层的褶皱。
We fabricated [Co/Cu] multilayers revealing a giant magnetoresistance (GMR) effect on free-standing elastic poly(dimethylsiloxane) (PDMS) membranes, The GMR performance of [Co/Cu] multilayers on rigid silicon and on free-standing PDMS is similar and does not change with tensile deformations up to 4.5%. Mechanical deformations imposed on the sensor are totally reversible, due to the elasticity of the PDMS membranes. This remarkable performance upon stretching relies on a wrinkling of GMR layers on top of the PDMS membrane.
