Název v původním jazyce

Electromechanical sensors based on carbon nanotube networks

Popis výsledku v původním jazyce

The network of entangled multiwall carbon nanotubes and composite consisting of PS filter-supported nanotube network are introduced as conductors whose conductivity is sensitive to compressive stress both in the course of monotonic stress growth and whenloading/unloading cycles are imposed. The testing has shown as much as 100% network conductivity increase at the maximum applied stress. It indicates favorable properties of multiwall carbon nanotube network for its use as a stress-electric signal transducer. To model the conductivity-stress dependence, it is hypothesized that compression increases local contact forces between nanotubes, which results in more conductive contacts. The lack of detailed knowledge of the mechanism as well as an unclear shift from individual contacts to the whole network conductance behavior is circumvented with a statistical approach. In this respect, good data representation is reached using Weibull distribution for the description of nanotube contact res
