Stretchable Electrodes: Negatively Strain-Dependent Electrical Resistance of Magnetically Arranged Nickel Composites: Application to Highly Stretchable Electrodes and Stretchable Lighting Devices (Adv. Mater. 19/2014)

On page 3094, Y. Hong and co‐workers develop a key enabling technology for stretchable displays sustaining their original pixel resolution even when stretched by using ferromagnetic conductive nickel composite electrodes and a hidden pixel structure. The hidden pixels connected via the composite electrodes are turned on under the tensile strain, thus sustaining the original pixel resolution due to the negatively strain‐dependent electrical resistance of the composite electrode.
