Production of Electric Voltage and Very High Surface Density in The Structure of CNTs Carbon Nanotubes    

Note: When the liquid passes through coils of single-walled carbon nanotubes, an electric voltage is created. This technique is used to make liquid flow sensors to detect very small amounts of liquids and also to generate voltage in nano biosensors applications . Also, conductive nanotubes with high ionic strength produce more voltage .Nanotubes have a very high surface density, which makes the nanotubes strong. It can be said that this property appears due to their remarkable smallness.
