Their approach employs a process that eliminates many drawbacks of previous fabrication methods, such as less conductivity or device failure, the team said.
"Our method does not require any secondary activation to make the material conductive," said Zhou, who also has affiliations with the Huck Institutes of the Life Sciences and the Materials Research Institute."The material can self-assemble to make its bottom surface be very conductive and its top surface self-insulated."
The material can also be 3D-printed, Zhou said, making it easier to fabricate wearable devices. The researchers are continuing to explore potential applications, with a focus on assistive technology for people with disabilities.
