Programmable patterned MoS2 film by direct laser writing for health-related signals monitoring

Summary: The two-dimensional (2D) transition metal dichalcogenides (TMDs) are promising flexible electronic materials for strategic flexible information devices. Large-area and high-quality patterned materials were usually required by flexible electronics due to the limitation from the process of ma...
