Stretchable electrodes are the most essential components of next generation devices such as IoT. It should be highly conductive, durable under repetitive stretching and have a small rate of change in resistance even with elongation. Most conventional electrodes are use a structure such as serpentine and buckle to reduce the resistance change. These structures alleviate the stress applied to the electrode when the electrode is stretched due to each shape, and the length of the electrode does not change, thereby minimizing the rate of change of resistance. Therefore, in this study, a conductive composite material having a structure inside the material was developed to overcome the disadvantages of such structuring. A conductive composite made by adding a hydrophilic material has a porous structure inside the material, so it has higher integration and conductivity compared to the existing structured electrode, while has a lower rate of change in resistance during stretching.
