This manuscript explores the effect of defect like surface waviness in double walled carbon nanotube based Nano mass sensors. Experimental images have reported that double walled carbon nanotubes (DWCNTs) are not straight and that they have a significant amount of waviness associated with them. It is also detected that CNTs do not inherit the same wavy thickness throughout their length. Hence a constant curvature or radius model may give uniform thickness in terms of curvature throughout the length which may lead to erroneous results. In this paper resonant frequency shift of double walled carbon nanotubes with deviations along its axis and different boundary conditions namely cantilever and bridged have been investigated. It has been observed that the defect significantly contributes to the dynamics of carbon nanotubes.
