— Correlation between mechanical deformation and conductivity behaviour of free-standing membranes of single walled carbon nanotubes (SWCNTs) has been successfully investigated. The aim of this study is proposing this kind of material as strain and pressure sensors. The nanotubes gauge factor of piezoresistivity has been evaluated by comparing the electrical responses induced by deformation in SWCNT membrane and in Si substrate: it proved to be factor 2.3-2.5 larger than that of the Si substrate.

The aim of this study is proposing this kind of material as strain and pressure sensors. The nanotubes gauge factor of piezoresistivity has been evaluated by comparing the electrical responses induced by deformation in SWCNT membrane and in Si substrate: it proved to be factor 2.3-2.5 larger than that of the Si substrate.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
