第一个高度可拉伸和敏感的自旋阀传感器的弹性膜上演示。传感器元件表现出稳定的GMR行为高达29%的拉伸应变在原位拉伸实验中，并显示超过500个负载循环没有疲劳。这种显著的拉伸性是通过预定的周期性断裂机制实现的，该机制在拉伸时产生曲折状图案。
The first highly stretchable and sensitive spin valve sensor on elastomeric membranes are demonstrated. The sensor elements exhibit stable GMR behavior up to tensile strains of 29% in in situ stretching experiments and show no fatigue over 500 loading cycles. This remarkable stretchability is achieved by a predetermined periodic fracture mechanism that creates a meander-like pattern upon stretching.
