Negatively Strain-Dependent Electrical Resistance of Magnetically Arranged Nickel Composites: Application to Highly Stretchable Electrodes and Stretchable Lighting Devices

摘要

In recent years, there has been an increasing interest in stretchable electronics. It has great potential in future electronics such as flexible displays, wearable electronics and biomedical applications. With recent progress in stretchable electronics, electronic devices on stretchable substrates can be protected from mechanical deformation by allowing the stretchable electrodes to undergo most of the mechanical stress. Previous stretchable electrodes were mainly realized by either vacuum deposition or inkjet-printing of metal thin films on elastomeric substrates. These stretchable electrodes show outstanding electrical performance at relatively low tensile strain conditions typically under 30% elongation.
