Structural Health Monitoring is a topic of growing significance in Civil and Mechanical Engineering, whereby an effective monitoring of a structure can lead to cost-effective maintenance and can enhance occupants' safety. A distributed monitoring system can better identify, localize and quantify incipient damages and variations of the structural behavior compared to a sparse utilization of off-the-shelf...
General equations are presented for the spatially dispersive conductivity, distributed impedance, Ohm's law relation, and transmission line model of both carbon nanotubes (CNTs) and solid material nanowires. It is shown that spatial dispersion results in an intrinsic (material-dependent) transmission-line capacitance. Spatial dispersion is numerically unimportant in metal nanowires, but leads to a...
We have investigated uniform carbon nanotube (CNT) dispersion in a solution and fabrication of CNT thin films on solid surfaces. To prevent bundle formation, we have examined surface modification of both the CNT surfaces and the substrate surfaces. To enhance the interaction between surfaces of the substrate and the CNTs, the substrate surfaces were made hydrophobic, because CNTs are generally hydrophobic...
