Title Development of Omnidirectionally Stretchable and Transparent Graphene Electrodes
Writer Engineering Date 2017-04-25 Hit 387

Stretchable and transparent electrodes have been developed for applications in flexible and wearable electronics. For customer-oriented practical applications, the electrical and optical properties of stretchable electrodes should be independent of the directions of the applied stress, and such electrodes are called omnidirectionally stretchable electrodes.

 

Prof. Ho Seok PARK reported a simple and cost-effective approach for the fabrication of omnidirectionally stretchable and transparent graphene electrodes with mechanical durability and performance reliability. The use of a Fresnel lens-patterned electrode allows multilayered graphene sheets to achieve a concentric circular wavy structure, which is capable of sustaining tensile strains in all directions. The as-prepared electrodes exhibit high optical transparency, low sheet resistance, and reliable electrical performances under various deformation conditions.

 

Furthermore, computer simulations have also been carried out to investigate the response of a Fresnel lens-patterned structure on the application of mechanical stresses. This study can be significant to a large variety of potential applications, ranging from stretchable devices to electronic components in various wearable integrated systems.

 

The research was conducted with the support of CAP business and published in one of the most world renowned research papers ACS Nano. The title of the study was “Omnidirectionally Stretchable and Transparent Graphene Electrodes.”
