Strain Sensor based on 3D graphene structure via microfluidic |
| 초록 |
These days, recent progress in designing graphene-based 3D structure shows new possibilities for various applications. Most of them are prepared by means of random self-assemblies of graphene oxide or graphene nanosheets. These methods have created the large-scale 3D structure like Graphene oxide aerogel, but, it is still challenging to generate well-defined 3d regular graphene structure. To overcome this limitation, we use microfluidic system for generating building blocks to generate 3D hierarchical graphene structures. After thermal reduction process, building blocks are transformed into 3D well-defined interconnected network structures with different electrical conductivity as reduction condition. Then, the resulting 3D closed-cellular structure serves as the strain gauge. And the strain gauge exhibited the gauge factor of around 4 and it shows excellent mechanical reversibility over 250cycles. |
