We demonstrate a new fiber-optic current sensor based on graphene nanoelectromechanical systems (NEMS) with a graphene membrane covering the hole on a fiber tip and two gold electrodes on opposite sides of the tip. The suspended graphene membrane will deform due to thermal effect when electrical current flows through it. Then the strain in the graphene nanomechanical resonator will change and it leads...
A microfluidic flowmeter is proposed based on graphene integrated “hot-wire” structure. A long-period fiber grating (LPFG) is written in a single mode fiber by CO2 laser to excite the higher-order mode. Graphene is coated around the grating to absorb the higher-order mode and generate the heat. The fiber is sealed into a home-made tube. When the microfluid flows through the graphene, the heat is taken...
The paper introduces concept and characteristic of method for social network analysis, and then it analyzes and evaluates structure attribute of traditional equipment support organization. According to the complexity characteristics of equipment support organization structure, it optimizes the organization structure, and by data analyzed, it summarizes that network topological structure of equipment...
